[[caption-width-right:350:Blue boy, pink girl, and no relation.]]

In fiction, and sometimes in RealLife, we tend to [[ColorCodedForYourConvenience differentiate between "girly colors" and boyish ones]]. It is clearer with babies, when we are prone to see girls dressed in pink and boys in light blue.

What's [[NewerThanTheyThink funny]] is that [[http://hueconsulting.blogspot.com/2007/03/why-is-blue-for-boys-and-pink-for-girls.html this is actually a recent development]]. In fact, in some cultures, [[http://www.cracked.com/article_19780_5-gender-stereotypes-that-used-to-be-exact-opposite.html it used to be the exact opposite]]: pink was associated with baby boys, because it's derived from red, which is considered a good masculine color (in some countries, it still is). Blue used to be feminine (and TrueBlueFemininity often still applies), as it was associated with the Virgin Mary.[[note]]And, in fact, for a time it was considered bad parenting to differentiate between genders until a few years after birth; that's why in some classic paintings you'll see boys in dresses.[[/note]]

Note that lots of female characters have had a pink motif that they wear with pride and sheer [[GirlyBruiser badassery]]. Male characters as well, because RealMenWearPink. But sometimes, pink is considered too childish and disrespectful, especially to an adult woman, so red may be substituted.

A variant of this trope that is surfacing lately is green for boys and purple for girls.

If there are TwoGirlsToATeam and one is represented by pink, the other girl will usually be represented by [[GracefulLadiesLikePurple purple]]. A purple girl can be anything from a {{goth}} to a {{tomboy}} to a ProperLady, while the pink girl is usually TheChick and/or a GenkiGirl. Purple has a variety of associations, not limited to PurpleIsPowerful and GracefulLadiesLikePurple - it's indicative of nobility and, by extension, nobility of character.

Can crop up in many BoysLove and GirlsLove stories; the active partner (''{{Seme}}'' in BL, ''OneeSama'' in GL) is unlikely to wear "girly" colors such as pink, but the passive partner (''{{Uke}}'', ''neko'') frequently does, and (especially in GL but sometimes in BL) may even have pink hair.

A SubTrope of PinkMeansFeminine, TertiarySexualCharacteristics, ColorCodedCharacters.

Compare TertiarySexualCharacteristics, RedOniBlueOni, ColourCodedForYourConvenience, PinkIsForSissies, PrincessesPreferPink. The opposite of this, MasculineGirlFeminineBoy, was originally named Pink Boy, Blue Girl.

Not to be confused with [[Franchise/{{Dragnet}} Blue Boy]].



* Huggies is a shining example of this trope. Go ahead, look 'em up on Website/YouTube, and link 'em back here.
* The second Snuggie commercial featured the generic grandfather, father, and son (and [[AllDogsAreMale dog]]) with dark blue snuggies. The grandmother, mother and daughter had pink snuggies.

[[folder:Anime & Manga]]
* In ''LightNovel/ChaosHead'', Rimi has pink hair and Takumi has blue.
* In ''Anime/ChouKuseNiNarisou'' ("I'll make a habit of it"), Nagisa Shiratori (pink hair) and her LoveInterest, Nosaka(blue hair).
* Takuto and Meroko from ''Anime/FullMoonOSagashite'' (the anime). Takuto is blue and Meroko is red (in the manga she wears black) but she keeps the pink hair. Averts the trope of happy pink girl×stoic blue boy because they are not a couple, ([[ClingyJealousGirl no matter how much Meroko wishes it]]).
* Shows up frequently in ''Anime/ShinkonGattaiGodannar'' with just about each of the couples/partners' pilot suits, noteably Goh and Anna. Even the more masculine of the two American female robot pilots were darker colors than her cohort (whose pink-and-white costume barely qualified as clothing).
* Pops up a lot in ''Franchise/{{Gundam}}''.
** In the original ''Anime/MobileSuitGundam'' and in ''[[Anime/MobileSuitGundamSeed Gundam SEED]]'', TheFederation had blue uniforms for male enlisted personnel and pink for females (officers wore brown regardless of sex). Later in the series, Cagalli gets a pink Gundam of the same type as Kira's(Blue-On-White) first suit.
* In ''Anime/MobileSuitGGundam'', the protagonist's fighting uniform is black with red, yellow, and blue highlights. His girlfriend's suit is predominantly pink.
** In ''[[Anime/MobileSuitGundam00 Gundam 00]]'', Soma Peries got a pink mobile suit in season 1 and Nena Trinity wore a pink pilot's suit. In season 2, they switch to red and purple, respectively. Played straight by [[http://i4.photobucket.com/albums/y143/gordon008/blog/Gundam00-01-LargePreview01.jpg Louise Halevy and Saji Crossroad]] in season 1. As well as [[http://images1.wikia.nocookie.net/__cb20090406012823/gundam/images/7/73/Setsuna_2312_A.jpg Setsuna F. Seiei]] and [[http://images3.wikia.nocookie.net/__cb20100204184911/gundam/images/e/e1/Feldt_Grace_2312.png Feldt Grace]] starting season 2. Setsuna and Feldt get bonus points for piloting blue Gundams with matching blue pilot suit and being a RoseHairedSweetie respectively.
* Hayate and Hinagiku from ''Manga/HayateTheCombatButler''. It's especially noteworthy as it completely subverts the girly pink-haired girl/stoic blue-haired guy dynamic (just don't tell that to Hinagiku) as Hayate is quite emotional at times and is noted for being very girly while Hinagiku is generally pretty tough and acts more boyish. Like the above example, Hina proves that girly pink can be very {{Badass}} and Hayate shows that being a slightly feminine {{Bishonen}} is also no handicap on that front.
* The FacelessMasses in ''Manga/HidamariSketch'' are often colored this way, whether they're hairless and limbless, shaped like restroom signs, or detailed in the outline but still a solid color.
* In various seasons of ''Franchise/{{Jewelpet}}'', there is the couple of Ruby and Granite. Both have wholly white fur, with the insides of their ears and accessories being pink and blue, respectively. Eye colors sort of count; Ruby's are red while Granite's are blue.
* In the original ''Anime/MagicalGirlLyricalNanoha'' mini-scenario of the ''VisualNovel/TriangleHeart3SweetSongsForever'' Lyrical fanbox, Nanoha and Chrono were rivals that became an OfficialCouple, with Nanoha having a pink motif and Chrono having a blue motif. These motifs were retained in TheAnimeOfTheGame even though the two of them weren't the OfficialCouple there anymore. Chrono's blue motif eventually led to him becoming AnIcePerson. Meanwhile, Nanoha's pink motif...well, the anime producers had ''way too much fun'' with Nanoha's pink motif by turning her into a pink PersonOfMassDestruction with a pink WaveMotionGun that fires giant pink beams that create huge pink explosions that have [[OhCrap left many people metaphorically crapping their pants]] as they stare into [[PowerGlows her pink glowy light]]. Girly pink is {{Badass}}.
* ''Manga/MagiLabyrinthOfMagic'' has [[spoiler:Aladdin's parents]] blue-haired Solomon and his eventual lover pink-haired Sheba.
* ''Manga/{{Naruto}}'': Sakura (pink-haired, dresses in pink and red) and Sasuke (blue-black hair, dresses in shades of deep blue).
* ''Manga/OnePiece'' has [[spoiler:Koala and Sabo.]]
* Jessie and James of Team Rocket from ''Anime/{{Pokemon}}'' have red and blue hair respectively. Their disguises often follow the same pattern, with James dressing at the blue end of the spectrum and Jessie at the red, though sometimes (as seen in "The Misty Mermaid") they'll switch ends.
* In case of ''Anime/PuellaMagiMadokaMagica'', it's more like TheChick wears pink and the {{Tomboy}} wears blue.
* Cheery, perky Manga/SailorMoon has pink, silver, white, or yellow hair in the original manga. Her predestined lover Tuxedo Mask has, depending on the image, dark black, blue, green, or purple hair. When he is married to Sailor Moon, he has pastel purple hair, which appears to be a symbol of his healing due to being with her. As far as costuming is concerned, though, Sailor Moon herself wears white and blue while Tuxedo Mask wears black and red.
** The 90s anime's {{Transformation Sequence}}s for the Sailor Starlights involved the background and their bodies changing from blue to pink as they changed from their male disguises to their true female forms.
* ''Manga/ShugoChara'':
** Amu and Ikuto.
** Nagihiko's Guardian Characters, the very pink and ([[{{Yandere}} sort of]]) girlish Temari and the very blue and boyish Rhythm.
** Also, Seiyo Academy's school uniforms follow the pattern as well, with the girl uniforms being red and the boy uniforms being blue.
* Toyed with in the ''LightNovel/{{Slayers}}'' franchise in regards to the two {{model couple}}s: for [[BodyguardCrush Lina and Gourry]], the latter wears blue while the former wears a light shade of magenta. For [[ShipTease Zelgadis and Amelia]], the latter is a princess who has both a pink dress for diplomatic duties and a modest traveling outfit with some pink touches, while the former is a chimera who literally has blue ([[AdaptationDyeJob or blue-green]]) colored skin.
* In both the anime and TheMovie, ''Anime/SpeedRacer'' typically wears blue and white, while his girlfriend Trixie dons pink and red. However, on formal occasions in the anime, Trixie would wear a blue dress while Speed wore a red blazer.
* A BL example are the title characters of ''LightNovel/{{Sukisho}}'' - with the {{uke}} having pink hair and eyes, while the {{seme}} has blue.
* Anyone who couldn't see the OfficialCouple of ''Manga/TokyoMewMew'' coming may have ignored this fact. Not only do Ichigo and Masaya have pink and blue hair, respectively (only in the manga, though; [[AdaptationDyeJob the anime changes them to red and black]]), but their last names are '''Momo'''miya and '''Ao'''yama! (meaning "peach" and "blue" in Japanese respectively.)
** Even more ironic, the whole Tokyo Mew Mew team is ''female'' and all the aliens are male. In the final battle, where Ichigo blasts her final attack, and Deep '''Blue''' releases the Mu Aqua, you can clearly see a clash of pink and blue.
* The Mu children in ''Manga/TowardTheTerra'' have pink dresses for girls and blue jumpsuits for boys. The adults all wear purple.
* If you look at colored manga pages, or often the anime uses this motif, for ''Manga/WanderingSon'' you'll notice it's not uncommon for male characters to wear blue and females pink. Considering the series is themed around gender it makes sense.
* The school uniforms in ''Anime/YuGiOh'' have the boys wearing blue jackets and pants and the girls wearing pink jackets.

[[folder:Board Games]]
* The ''Game of Life'' board game is an example of this. Boy pegs are blue, girl pegs are pink. Interestingly, the rules say you have to put a second peg in your car when you get married, but they don't say [[HoYay what color the peg has to be]].

[[folder:Comic Books]]
* The mutant twins ComicBook/{{Quicksilver}} and ComicBook/ScarletWitch often wear blue and red costumes respectively, although Quicksilver's first costume was green.
* The stars of ''ComicBook/SunnyvilleStories'' display this trope in color artwork; Rusty wears blue (or red) while Samantha wears pink.

[[folder:Comic Strips]]
* {{Conversed}} in ''ComicStrip/FamilyCircus'', January 28, 2008:
-->''The WesternAnimation/PinkPanther is a girl. If he was a boy he'd be the Blue Panther.''
* In colored printings of ''ComicStrip/ShermansLagoon'', Sherman (a male great white shark) is gray -- slightly bluish, depending on the inks used -- and his wife Megan is purplish-gray.

[[folder:Fan Works]]
* Inverted to a degree by Ryan Lee and Susan Chan in ''FanFic/FutariWaPrettyCureDragon''; the manly martial artist Ryan [[RealMenWearPink wears pink]], and the {{Ojou}} and LadyOfWar Susan [[TrueBlueFemininity wears blue]].
* Played with by Haruhi and Itsuki in ''FanFic/SOSPrettyCure''; {{Shorttank}} Haruhi's theme color is actually red, and AmbiguouslyGay Itsuki's is purple. Played straight with Mikuru and Kyon; Mikuru's theme color is pink, and while Kyon's theme color is a dull brown (it even shows in his Cure costume), his aura as a Cure is blue.
* Played straight in ''FanFic/FutariWaPrettyCureDimensions'' by the very tomboyish Megumi Yamada and the somewhat effeminate Ken Ichida, who also happens to be the blue boy to another tomboy who likes pink--his own sister, Chiyoko.
* In ''FanFic/RhythmicPrettyCure'', at the karate school Hitomi and Tsumugi go to on Mondays and Thursdays, the boys' karategi is blue, and the girls' karategi is pink.
* In ''Literature/HarryPotter'', [[VoluntaryShapeshifting Tonks]] usually went around with spiky pink hair. We don't see much of her [[spoiler:son, Teddy]] in the books, but {{Fanon}} has largely agreed that his hair should be [[YouGottaHaveBlueHair blue]].

[[folder:Films -- Live-Action]]
* ''Film/TheAdventuresOfSharkboyAndLavagirl'': Sharkboy and Lavagirl wear blue and red respectively, with Lavagirl also having pink hair. This also comes with ColorCodedElements as Sharkboy has water powers and Lavagirl has fire powers.
* Literature/BridgetJones wears a lot of girly outfits. But the second film has her in a lot of girlier outfits with pink items in rotation, in contrast to her boyfriend's blue business suits. This even shows up on the [[http://www.impawards.com/2004/bridget_jones_the_edge_of_reason_ver2.html Poster and DVD covers for the film]] with a pink and rose-patterned clad ReneeZellweger is flanked by the blue-clad HughGrant and ColinFirth.
* While it's not very prominently featured, Sharpay and Ryan Evans of ''Film/HighSchoolMusical'' occasionally plays this trope. The gym scene from their ''"I Want it All"'' song has them wear pink and blue sports outfit, while ''"A Night to Remember"'' shows them getting ready in similarly coloured bathrooms. Also, Sharpay is shown to ride a bright pink convertible, while Ryan has a blue motorbike.

* In one of the ''Literature/{{Xanth}}'' novels, the male and female main characters had switched bodies due to a magic spell gone wrong. When they manage to acquire clothes from a clothes tree, they take colors according to their mental gender, much to the confusion of their semi-sentient horse.
* Stephen King's Dark Tower series features the sentient monorail Blaine and his 'sister', Patricia. They feature the reversed color scheme: Patricia is blue, and Blaine is pink.

[[folder:Live-Action TV]]
* In earlier seasons of ''Series/{{Smallville}}'', Lana always wears pink and Clark always wears blue.
* Made fun of in an episode of ''Series/TheFreshPrinceOfBelAir'', where Ashley asks how they could tell from the sonogram if Vivian's baby was a boy or a girl.
-->'''Hilary:''' Oh, Ashley, you are so naive. If it's a boy, it's ''blue''!
* [[Franchise/SuperSentai Pink]] [[Franchise/PowerRangers Rangers]] are always female. Blue Rangers are often male, but have been female a number of times. Out of the most common suit colors (Red, Blue, Yellow, Pink, Green, Black, and White), Green and Black (usually seen as interchangeable) are the only all-male colors (except in ''Series/KaizokuSentaiGokaiger'', see below).
** Also, while the Pink Ranger is usually TheChick, more recent seasons have been subverting this (starting with ''Series/MiraiSentaiTimeranger'' and ''Series/PowerRangersTimeForce'', where Pink is the real team leader even if Red gets the official recognition). The most common inversion comes on teams with two girls, where Pink will be the level-headed CoolBigSis while Yellow will be TheDitz.
** Interestingly, this also extends to ''Series/KaizokuSentaiGokaiger'', where the Rangers have the power to assume the forms of their predecessors (complete with DistaffCounterpart costumes where necessary). Thus far, Pink Ranger Ahim is the only person to use any Pink Ranger Keys, while every other color has been used by people of both genders (except, again, for Green).
*** This is averted in the Gokaiger Vs. Gavan movie, where the whole team change into pink Sentai warriors.
* ''LazyTown'''s two main characters fit this trope. Stephanie wears pink and Sportacus wears blue.
* The GameShow ''Series/{{Scrabble}}'' did this with its contestants' nametags.
* Lampshaded and played with in a stand up routine by Israeli comedian Uri Hezkiah. In Hebrew, almost every word grammatically ''has'' to have a gender, depending on who is spoken of or who is doing the speaking. Uri muses that since babies all look the same, the only way to know whether you should pick up your friend's baby and say "That's a cute baby boy" or "That's a cute baby girl" is whether it's dressed in blue or pink. He then says "But imagine you find a baby dressed in orange. What do you do? You can't risk offending your friend". After some thought, he picks up an imaginary baby and says "Why, that's a cute... organism!"
* In one episode of the American version of ''Series/{{The Office|US}}'' an employee brings her baby boy to the office (dressed in pink). Pam tells the mother "she's so cute" only to have her say he's a he. When Pam explains she thought the baby was a girl because of the pink clothing the mother responds with "Pink is his favorite color."
* In ''Series/{{Friends}}'' Faded Salmon is confused for being pink, and thus [[PinkIsForSissies not a color for guys to wear]].

* The song ''You're a Pink Toothbrush'' applies this trope to romance between inanimate objects.
* Referenced in the first stanza of Joe Jackson's song "Real Men".
* [[http://www.youtube.com/watch?v=OtdC8d8FmIA This video.]]
* The more well-known Music/{{Vocaloid}} characters are [[ColorCodedForYourConvenience differentiated by hair and/or outfit color]]; true to the trope, pink-haired Luka is a girl and blue-haired Kaito is a boy. Inverted with Miku, who has light blue hair and is a girl.
* The music video for Stromae's [[https://www.youtube.com/watch?v=CAMWdvo71ls Tous Les Mêmes]] uses pink lighting to denote a "female" point of view and green to denote a "male" point of view.
* Used in Benny's [[Little Game https://www.youtube.com/watch?v=WNr3x1kVVEc]] video, where girls and boys are dressed in their respective colors, and forced into gender-approved behaviors. By the end of the video, they're all covered with blue ''and'' pink.

* Sanrio's [[HelloKitty ''Little Twin Stars'']] [[http://media-cache-ec0.pinimg.com/236x/c0/90/30/c0903035efc3d3151bb7ce33facc8c3b.jpg is a classic example: just look at their hair.]]
* Inverted in ''{{Bionicle}}''. The females still retain the "pink" personality, but the majority of the female main characters are blue. And while there are no pink characters, the red ones are all male.
* Creator/FisherPrice WesternAnimation/LittlePeople toys and playsets usually avert this, with characters wearing whatever they realistically would. However, Fisher-Price has started making all-pink sets. What makes this stupid is that they are simply recoloring old molds, usually ones with normal colors. So now girls can buy a pink (instead of yellow) bus or dump truck, and a pink (instead of white and blue) plane. And a pink house, which is identical to the normal house in mold, except pink. It's borderline condescending and, since the main difference between the two molds is one is entirely pink, completely insulting.
** And not just Little People. If you look through the F-P toy line, you'll also see blatant examples of this. The ''Laugh and Learn'' Puppy plush comes in both "regular" and "pink" versions (where the only difference is that the plush fur and ears is ''pink''- thankfully, they're fixing that- by giving Puppy a sister who has pink ears and ''likes the colors pink and purple''). Heck, even their ill-fated ''[=PowerTouch=]'' reader system came in silver and blue for boys, and ''pink and purple'' for girls.
* Many toys from V-Tech usually also fall squarely into this trope- many toys come in both pink for girls and blue for boys, and the only difference is the toy color. Other toys from the company tend to come in regular non-pastel shaded colors for boys, but still have a pink version aimed squarely at young girls.
* Variant used in Franchise/LeapFrog toys: Green for boys and purple for girls.

[[folder:Video Games]]
* Maria Luna of ''BackyardSports'' loves the color pink and plays better when she wears it. In an aversion, Jocinda Smith loves blue.
* ''VideoGame/BubbleBobble'': One of [[MovesetClone the original two]] is the underdog Bob, who is a male human-turned-blue bubble dragon. His apparent partner in ''Bubble Symphony'' (in cutscenes, she is ''always'' beside Bob) is Coro, a female human-turned-magenta bubble dragon and one of the new group of two. Extended with green for Bub (a boy) and orange for Kulu (a girl), who are also beside each other in cutscenes.
** ''Bubble Bobble '''[[NonLinearSequel Part]]''' [[NonLinearSequel 2]]'': In the NES version's intro, the protagonist who soon gets [[BalefulPolymorph cursed]] wears (light greenish) blue, and the soon to be DamselInDistress wears pink with a matching color bow.
* Inverted in ''VideoGame/CastlevaniaPortraitOfRuin'': Jonathan's outfit is red, while his menu items are red or pink. Charlotte's outfit (including underwear!) are blue, as are her menu items.
* ''VideoGame/CommandAndConquerGenerals'' has an... extreme variation on this trope amongst the USA faction: Normally, the faction's superweapon is a blue PillarOfLight being reflected off a satelite to form a KillSat system. But play as the female general from their faction, and the beam turns a lovely shade of pink.
** Said general is titled the "Superweapon General" however, so it is possible to {{handwave}} the color change as being part of some prototype technology.
* The ''VideoGames/IceClimbers'', Nana and Popo, play this trope straight. Popo wears a blue parka while Nana wears a pink/red one.
* [[AdventuresOfLolo Lolo and Lala]] also play this trope straight. Lala [[TertiarySexualCharacteristics even wears a bow]].
* Lolo and Lala's [[Franchise/{{Kirby}} Dream Land-dwelling]] {{Exp|y}}ies, Lololo and Lalala, are naturally also guilty of this. However, the title character of their series is a pink boy.
* In ''VideoGame/FinalFantasyIVTheAfterYears'', PolarOppositeTwins Palom and Porom wear blue and pink, respectively. Porom even has pink ''hair'', despite Palom and her younger self both having brown hair.
** ''VideoGame/FinalFantasyTacticsAdvance'' has Marche (the Blue Boy) and Ritz (the Pink Girl).
* ''Videogame/FinalFantasyXIII2'': Serah in pink (and white, with lots of revealing holes) and Noel in blue for their original costumes.
* In ''VideoGame/FireEmblemTheSacredStones'', the under-leveled recruit Amelia wears pink in her portrait, yet wears blue in battle scenes. At least, until she achieves higher ranks, in which case she wears pink armor ''[[CuteBruiser even as a general]]''.
* In ''VideoGame/GoldenSun'', all three pairs of villains (with the possible exception of Agatio, who looks more green than blue) are dressed like this. There's also [[RedOniBlueOni Jenna and Piers]] from the second game.
* ''VideoGame/MonsterHunter'': One of the three subspecies of Rath (including the general red/green variant), manifests itself in the Azure Rathalos and Pink Rathian.
** In an {{inver|tedTrope}}sion, the red-and-pink Teostra are male, while the blue Lunastra are female.
* ''VideoGame/NightsIntoDreams'', another SEGA franchise from Sonic Team, has Claris (pink hair and eyes) and Elliot (blue hair and eyes), both examples of CurtainsMatchTheWindow as well.
** And then NiGHTS itself is mostly purple and [[ViewerGenderConfusion nobody can tell]] [[AmbiguousGender which gender it is]].
* ''VideoGame/{{Persona 3}} Portable'' has different color-coded menu screens depending on the gender the player selects for their protagonist -- naturally, pink for the girl and blue for the guy.
** The first two party members to join the MC follow this theme as well; Yukari is almost never seen without wearing something pink, and Junpei, apart from his blue shirt, ''never'' takes off his blue hat.
* Princess Zelda, in ''[[VideoGame/TheLegendOfZeldaOcarinaOfTime Ocarina of Time]]'', predominantly wears pink (like many of her [[PrincessesPreferPink ancestors and descendants]]). When disguised as the male-looking Sheik, however, she wears blue.
** Notably averted in some of the games, however. Zelda wears blue and white in ''[[VideoGame/TheLegendOfZeldaALinkToThePast A Link to the Past]]'', and in ''[[VideoGame/TheLegendOfZeldaTwilightPrincess Twilight Princess]]'', she wears purple and white.
* ''LegendaryWings'' has Michelle Heart [[note]]Japanese version, the overseas version has her outfit changed to green[[/note]] and Kevin Walker.
* Subverted in ''VideoGame/PanelDePon''; Sharbet and Elias both have primarily blue color schemes and are both female, like the rest of the fairies.
* ''Franchise/{{Pokemon}}'' has an inversion: Male members of the Nidoran family are pink and purple. Female members are blue.
** The shiny versions, however, play the trope straight (with the exception of Nidoqueen, whose shiny version is predominantly green).
** Latias and Latios (twin dragons and legendary Pokemon) are red/female and blue/male, respectively.
** Starting from the third generation onward, the font color on certain game menus (like the save screen) will be either blue or red/pink depending on whether the player character is male or female, respectively. In the fourth-generation games, the Poketch and the Pokegear are similarly color-coded.
*** Also, the text of [=NPCs=] in ''[=FireRed=]'' and ''[=LeafGreen=]'' will change color depending on their gender - red for girls, blue for boys, black for Pokemon and computers.
** ''VideoGame/PokemonBlackAndWhite'' has the Water/Ghost jellyfish Jellicent. Males are blue with a large mustache, while females are pink, lack a mustache, and [[TertiarySexualCharacteristics have lipstick and eyelashes]].
* ''ProfessorLayton'''s young companions fit the trope. His apprentice, Luke, wears a blue hat and blue sweater, while his adopted daughter Flora wears a pink hair ribbon and either a white and pink (''CuriousVillage'') or pink and brown (the other games) dress.
* In ''VideoGame/ResidentEvil2'', the main playable characters are also color coded in this way, with Leon in a blue uniform and Claire in a pink 'biker' outfit.
* Amy Rose and ''Franchise/SonicTheHedgehog'' of the eponymous series. Since the Dreamcast era, Amy has been wearing all red to go with her pink fur. [[HalfDressedCartoonAnimal Sonic, on the other hand...]].
** This does bring up some confusion at one point, as [[spoiler:the animal inside the rather masculine E-102 is a pink bird]].
** The default Extreme Gear for male Xbox Live Avatars in ''[[VideoGame/SonicRiders Sonic Free Riders]]'' is blue, while its female equivalent is pink. The description of the latter lampshades it.
-->''This model from Accelovice's women's line is a favorite among female riders. The fact that it's pink doesn't hurt!''
* Jacques (the Blue Boy) and Aila (the Pink Girl) from ''SuikodenIII''.
* ''Franchise/SuperMarioBros'': Although he is associated with the color red because of his hat and shirt, Mario's outfit also includes blue overalls, and his love interest, Princess Peach, wears pink.
* The exclusive robots of the protagonists of ''VideoGame/SuperRobotWarsAdvance''. Axel Almer gets the blue [[MotionCaptureMecha Soulgain]], whereas Lamia Loveless gets the pink [[WingedHumanoid Angelg]].
* ''VideoGame/TalesOfPhantasia'' has pink-haired Arche and her blue-haired boyfriend Chester.
* Inverted in ''VideoGame/TalesOfSymphonia'': Colette, chosen of Sylverant, wears a blue and white robe. Zelos, the chosen of Tethe'alla, wears pink.
* Milla and Jude, the dual protagonists of ''VideoGame/TalesOfXillia'' are colour-coded this way, reflected in both their outfits and the colour of the game menu depending on which of their routes is currently being played. Inverted by the BigBadDuumvirate, in a deliberate attempt to contrast them with the heroes: [[spoiler: Muzet wears light blue and white to contrast Jude's dark blue and black outfit, and Gaius wears dark red and black to contrast Milla's pink]].
** Also inverted by Milla and Jude themselves in [[VideoGame/TalesOfXillia2 the sequel]], where Jude wears a red shirt under his lab coat and Milla's white outfit has blue accents.
* ''VideoGame/TwinCobra II'': Player 1's helicopter is blue and is piloted by a male, Player 2's helicopter is red and is piloted by a female.
* In ''VideoGame/{{Twinbee}}'', the blue Twinbee and the pink Winbee (which also has a heart-shaped cockpit) are piloted respectively by Light and his girl cousin Pastel, who wear the same colors as on their ships.
* This is the colour scheme most often given to Akari and Ricky in ''1080'' and ''Wave Race'', those two being implied to be a couple.
* In ''VideoGame/AWitchsTale'', Gretel wears pink while Hansel wears blue. Otherwise the two girls dress quite similarly.
* {{Inverted|trope}} in ''Videogame/DragonBallOnline'', in which male Majin's are pink and females are blue. Player character Majins can switch it though, or be gray.
* Both ''VideoGame/MegaManBattleNetwork'' and ''VideoGame/MegaManStarForce'' have the main character (Mega Man) decked out in blue and a close female friend (Roll and [=Sonia/Harp Note=] respectively) who wears pink.

[[folder:Web Comics]]
* In ''Webcomic/MotherlyScootaloo'', as a ContinuityNod to the theme of the canon episode [[Recap/MyLittlePonyFriendshipIsMagicS2E12BabyCakes Baby Cakes]], Lightning has a blue [[http://motherlyscootaloo.tumblr.com/post/36712378649/there-will-be-a-short-break-between-the-end-of set]] [[http://motherlyscootaloo.tumblr.com/post/37600596997 of]] [[http://motherlyscootaloo.tumblr.com/post/37677330400 baby]] [[http://motherlyscootaloo.tumblr.com/post/37721792369/askdiscordwhooves-what-if-you-were-really pajamas]], courtesy of Ponyville General Hospital.
** Also, [[http://motherlyscootaloo.tumblr.com/post/40315271830/askdiscordwhooves-self-worth-the-longer-you a number of the furnishings of his room are blue]].
* Used in ''Webcomic/VGCats'' with Leo (who wears blue and has grey fur) and Aeris (who wears mainly purple-pink clothes and has pink fur).
* Commented on by Millie in ''Webcomic/OzyAndMillie''; one about her needing to 'staple pink frilly stuff' to herself to remind Stephan that she's a girl, and another where she thinks pink is a bit of a girly colour for herself. The pink here is her own skin after being hit with the defoliation RunningGag that Simpson had set up. As far as fur colour is concerned, Ozy is white-grey (Arctic fox), while Millie is red-orange (red fox). Make of that what you will.

* The website [[http://www.girlsaskguys.com/ Girls Ask Guys]] uses this scheme to differentiate between male and female users, by highlighting their username, their 'rank', and, if asking the question, their rating stars with the respective colour. If the user has not yet chosen an avatar, they sport a silhouette of their gender with the corresponding shade, too.
* The two authors of ''Blog/CinnamonBunzuh'' distinguish their text from one another by having one in pink and the other in blue.

* The "[[http://en.wikipedia.org/wiki/Grammatical_gender Grammatical gender]]" article on Wiki/{{Wikipedia}} is illustrated by a cartoonish image of a male and female cat; they look exactly the same, but the former wears a blue bow on its tail and the latter, pink.
* Discussed in WebVideo/TheNostalgiaChick's [[http://thatguywiththeglasses.com/videolinks/thedudette/nostalgia-chick/16616-the-smurfette-principle analysis]] of the [[TransformersGeneration1 original ''Transformers'' cartoon]], referring to both {{A|ction Girl}}rcee and [[LadyOfWar Elita One]]. Elita One was the DistaffCounterpart of Optimus Prime, and so (leader/girl) pink to his (leader) red and (boy) blue coloring. Elita One's AmazonBrigade otherwise had nothing with the trope, her soldiers appearing in all kinds of colours. Arcee, being [[TheSmurfettePrinciple the one girl]] starting the third season, was pink, and so was her (intended) love interest Hot Rod in a magenta shade ("aging" to red when he became Rodimus Prime). From there, the trope gets interesting in that pink is a noticeable colour choice among the Autobot females, but also among the Decepticon males (though not much in the cartoon because that ended long before the toyline did). [[BigEater Hun-Grrr]], [[ExactlyWhatItSaysOnTheTin Misfire]], the {{Sea| Monster}}cons, [[BigEater Skullcruncher]], Spinister, Fangry, [[{{Badass}} Gaihawk]], Barricade, Roller Force, and Horri-Bull, among others, all sport a good level of pink. Blue is more equally divided between the factions.
* In [[https://www.youtube.com/watch?v=zsxwKKyHmjI this vlog]] a young girl unboxes a pair of [[PrettyInMink rabbit fur coats]] her parents bought her, one dyed pink and the other blue.

* From the ''WesternAnimation/AdventureTime'' episode "The Silent King", regarding a blue mirror, "And it's painted baby blue, boy style!"
** In terms of the show, Finn is a Blue Boy to the Pink Girl Bubblegum.
*** Also, Ice King and Princess Bubblegum.
** Inverted in [[GenderFlip "Fionna and Cake"]], however.
* In ''WesternAnimation/TheFairlyOddparents'', Timmy Turner's clothes are all pink because his parents were expecting a girl.
** In-universe. Butch Hartman had intended for them (or at least his hat) to be blue, but when his blue marker ran out before he could finish, he had to use a pink one instead.
* In the episode of ''{{Pocoyo}}'' where he meets an alien, when the alien's parents turn up, the {{Narrator}} addresses the pink alien as the "Mummy Alien". The Alien then gives an angry look at the screen and the Narrator corrects himself, realizing it's the "Daddy Alien".
* ''WesternAnimation/BluesClues'' played it differently - Blue is blue and is female, but Magenta, who is pink, is also female.
* In ''WesternAnimation/TinyToonAdventures'', Buster is a blue bunny, and Babs is a pink one, and (even though they say that they're not related) sometimes they'll even break out matching props.
* Yin and Yang from ''WesternAnimation/YinYangYo'' are a pink bunny and a blue bunny respectively as well.
* Flavio and Marita the hip-hippos from ''WesternAnimation/{{Animaniacs}}'' are blue and pinkish-purple respectively.
* Because Creator/{{Disney}} dates to the early decades of the 20th century, the idea that blue represented calm, soothing, feminine attributes was still popular (with red/pink as the guy hero color). Due to this, many of Disney's early female characters from the first golden age are swathed in blue; Pink Girl Blue Boy would emerge slowly but surely much later on.
** [[ClassicDisneyShorts Minnie Mouse]] has been seen in many colors, but for most of her early color appearances, she was never seen in pink (pink colorations of old cartoons not counting). Merchandise and the comics would paint her whatever the heck they wanted; but blue was a color that she appeared in frequently. Best of all, the blue contrasted with Mickey's standard guy-hero red. The all-pink wouldn't emerge until the late Pluto cartoons, and the ever-famous red dress with white polka dots wouldn't come in until Disneyland was opened. In modern animated appearances, Minnie bounces back and forth the most between wearing soft blue to contrast Mickey, or bright red to match him. [[TokenGirl That doesn't stop marketing from dousing her home, her wardrobe, and her merchandise pink, of course]].
** The artists debated long and hard on what color {{Disney/SnowWhite|AndtheSevenDwarfs}} should be dressed in, even testing out the (at the time) unusual idea to dress her in all pink, but in the end, they went with the easy-on-the-eyes blue bodice. Her prince, of course, brought the red cape.
** The Blue Fairy from ''Disney/{{Pinocchio}}'' (and the only chick in the film, no less. Cleo doesn't count). This might be because in the original tale her name was the Fairy with Turquoise Hair. The blue becomes more noticeable, though, when contrasted with Pinocchio's red lederhosen ([[ArtisticLicense heeey, that's not Italian!]]).
** Disney/{{Cinderella}} is debatable. Her dress is silver in the movie but blue in all follow-up merchandise in the Disney Princess line. The two dresses she wore as a child and her nightgown are blue.
** Alice from ''Disney/AliceInWonderland'' wears a blue dress, [[http://www.bkkbooks.com/image/Alice-Adventures-in-wonderland.jpg as in the original illustrations from the book]].
** Wendy from ''Disney/PeterPan'' wore a blue nightdress, while her younger brother Michael wore pink pajamas.
** In ''Disney/LadyAndTheTramp'', Lady has a blue collar, and Tramp gains a red collar at the end of the movie. Meanwhile, the baby in the movie is a boy, but his entire room and pajamas are pink.
** When the infant is shown he's always wearing pink. The sequel however, which is from the 2000s, gave him blue likely as the color had long changed to be feminine.
** Another dog example in ''Disney/OneHundredAndOneDalmatians'' lies with Pongo, who sports a red collar, and Perdita who sports a blue one. It's not clear whether this extended to the puppies or not, since we only know the name and gender of three: Lucky, Rolly, and Patch, all males and all in red. In the animated series, there's definitely not a theme; Rolly and at least one other male (either Wizzer or Dipstick) had blue collars.
*** Tie-ins for this movie are notorious for getting this messed up. Often, Pongo and Perdita's collars will be switched, or some of them will be pink instead of red... actually, on the cover of the first VHS release, several of the puppies had magenta, purple, and even yellow collars.
** The trend is shattered, though, in the late 1960s, where one would find girls popping up more frequently in purples and pinks ([[Disney/TheJungleBook Shanti]], [[Disney/RobinHood Maid Marian]], [[Disney/TheRescuers Bianca]], [[Disney/TheBlackCauldron Eilonwy]], [[Disney/{{Hercules}} Megara]], [[Disney/TheHunchbackofNotreDame Esmeralda]]), girls wearing whatever the movie would require (Disney/{{Pocahontas}} in tan...but with a blue necklace), and then finally, girls who took both blue and pink/red in stride. Examples of pink-and-blue sharing being:
*** [[Disney/SleepingBeauty Aurora]] is a rare example from 1959. The three good fairies weren't sure how to color code Aurora, as blue was the traditional feminine color and pink was the emerging feminine color. Note how throughout most of the movie Aurora is wearing blue, but in the Disney Princess line she is ''always'' in pink. [[MisaimedMarketing Hmmmmmm.]] Prince Phillip brings a red cape and hat to the party. Disney Princess-gear Aurora always wears pink because Cinderella always wears blue (Belle wears her yellow ballgown, and Snow White is a mixture of red, blue, and yellow). Aurora was changed over to the pink dress to get guests to stop mixing her up with Cinderella. Whether or not this problem truly arose in the Disney parks is not certain (of course, since so few guests seem to know who Aurora even ''is''...)
** [[Disney/TheLittleMermaid Ariel]] had not just a blue dress, but a pink one as well. A portion of the fandom has since complained about the pink dress clashing with her aggressively red hair...but one must remember that it ''was'' the late 1980s (the tiles on the floor in that scene are black-and-white checkerboard. Natch). Notably, she wears a turquoise dress at the theme parks.
** Belle is a more modern version of strictly blue; she wears blue throughout most of the movie, and it's what set her apart from the autumn-themed villagers. She also has a fancier pink dress which appears briefly once she and the Beast begin to get along. However, thanks to the Disney Princess line, it's a gold ball gown that she's primarily associated with, instead of her blue peasant garb. When Belle wears blue, the Beast wears a red cape. When she wears gold, the Beast is the boy in blue. Note that Gaston wears red.
*** There's a reason Belle wears that blue dress. If you pay attention, you'll notice that out of all the characters in that movie, only two wear blue.
** Jasmine from ''Disney/{{Aladdin}}'' is another modern example of strictly-blue; but this might have been incidental, because throughout the whole movie [[GoodColorsEvilColors Blue was Good and Red was Evil]]. Her GoGoEnslavement outfit is red. Notably, Aladdin himself is associated with the color purple because he has both good and bad qualities. He's a thief but steals to survive, and shares with those even less fortunate than he.
** Disney/{{Mulan}}'s primary color is, believe it or not, ''green'', that being the color of both her armor and the dress she wears at the beginning of the film. She has two outfits of different colors: the pink-with-blue-trim fancy gown she's forced to wear for her disastrous meeting with the Matchmaker, and a [[FauxSymbolism blue-with-red-trim]] dress she wears at the end of the film, when she defeats the Huns and proves herself. Shang also brought out a red cape...but this might've been due to the story's cultural setting.
** [[Disney/TheGreatMouseDetective Olivia]], [[Disney/OliverandCompany Jenny]], [[Disney/AtlantisTheLostEmpire Kida]], and [[Disney/TreasurePlanet Captain Amelia]] carry on the grand tradition of strictly-blue-girls. Dr. Doppler, who Amelia hooks up with, is even kind enough to wear a red jacket next to her blue one. Aww.
** In ''Disney/{{Fantasia}} 2000'', Donald wears a red robe and Daisy wears a blue one.
** Inverted in ''WesternAnimation/{{Cars}}'', where hero Lightning [=McQueen=] is a red race car, while his love interest Sally is a blue Porsche 911 Carrera. Also inverted with two of the background race cars where the pink race car sponsoring Tank Coat is actually male, and the blue race car sponsoring [=RevNGo=] is actually female.
*** Played straight with Finn [=McMissile=] and Holly Shiftwell from the sequel, however, as with the kissing couple seen on the bridge in Paris.
** In the Pixar animated film ''WesternAnimation/ABugsLife'', all the female ants are pink, while all the male ants are blue.
** A straight example would be ''Disney/{{Tangled}}'', where Literature/{{Rapunzel}} wears pink, lavender, and purple and Flynn wears blue.
** Also inverted in ''WesternAnimation/FindingNemo'' where we have Marlin, an orangey-red clownfish, and Dory, a blue regal tang.
** Played straight in ''WesternAnimation/LiloAndStitchTheSeries'', where Stitch is blue and Angel (#624 and his love interest) is pink.
* In ''DragonTales'', the main cast of dragons (assuming you count Quetzal as supporting) is certainly this way. Ord is blue; Cassie is pink. Zak and Wheezie, who are a two-headed dragon, are divided colorwise ''down the middle'': the Zak half is green, while the Wheezie half is purple.
* Parodied in ''WesternAnimation/FamilyGuy'', where a talking blue car is hitting on a pink car but realizes that it's his buddy, whose owner gave him a paint job.
** Though, at the last second of that particular CutawayGag, it is implied that the pink car is gay/bi, at least.
** Meg's clothes are pink and Chris wears blue.
* In ''WesternAnimation/HeyArnold'', Harold and Helga, who are the two main bullies of the fourth grade, are represented with blue and pink, respectively. However, Helga often calls Harold "pink boy" in reference to his ruddy skin tone.
** Arnold is also regularly associated with blue, due to his jumper and hat.
* Dottywot and Spottywot, respectively, in the British preschool series ''The Wotwots''.
* The first two cars to be crushed to death during the song "Worthless" from ''WesternAnimation/TheBraveLittleToaster'' are actually a male blue car and a female pink car, respectively.
* Gumball and Anais, the lead character and his little sister in ''WesternAnimation/TheAmazingWorldOfGumball''. The color motif is inverted with their parents, Richard and Nicole.
* ''WesternAnimation/RegularShow'': Mordecai is a blue jay and Margaret is a red-breasted robin (filling in for Pink).
* The ChristmasElves from ''RudolphTheRedNosedReindeer''.
* Inverted and played straight with Charlotte in ''MakingFiends''. She's a stereotypical, over-the-top caricature of everything [[{{Moe}} adorable]] and annoying about the archetypal American little girl, but has baby blue as her [[AmazingTechnicolorPopulation color]] and motif. Still, she seems to love pink as much as expected, as almost all of her possessions are pink.
* [[RoseHairedSweetie Molly]] and [[YouGottaHaveBlueHair Gil]] from ''WesternAnimation/BubbleGuppies''. Bonus points for being not only the two characters featured most prominently, but also an ''extremely'' [[ShipTease played with]] ToyShip
* Rosie from ''ThomasTheTankEngine'' is a female pink tank locomotive. This is especially noticable when she is seen with Thomas, a blue tank locomotive.
* In ''WesternAnimation/{{Gargoyles}}'', the gargoyles' eyes will actually glow a different color depending on that gargoyle's gender: females' eyes glow red, while males' glow white. Inverted with the clones, however.
** There's a good reason why all the females have glowing red eyes: originally, [[BigBad Demona]] was going to be the only red-eyed gargoyle, but since the show's writers did not want to make her role as the villain more obvious, they changed it so that ''every'' single female gargoyle has red eyes and not Demona.
* Princess Cadance and Shining Armor as one of the few [[OfficialCouple canon couples]] in WesternAnimation/MyLittlePonyFriendshipIsMagic.
** When the newborn Cake twins are introduced, their swaddling clothes are blue for colt Pound Cake and pink for filly Pumpkin Cake.
* In ''WesternAnimation/JellyJamm'', Rita and Mina fit the "pink girly girl, blue tomboy" subtrope. Averted with the male characters, however, as two are purple and one is red.
* Contact and Live Wire (No, not [[Franchise/{{Superman}} that one]]), and Charge from British TV series ''The Lampies''.
* {{Inverted|Trope}} in the TV series ''ComicStrip/KrazyKat''; Ignatz Mouse (the boy) is pink while Krazy Kat (the girl) is blue. [[AmazingTechnicolorWildlife They were similarly colored]] in the original comic strip but, as [[AmbiguousGender Krazy's gender was ambiguous]], this trope did not come into play at all.
* In ''WesternAnimation/SouthPark'' Stan wears a blue hat with a red poofball on top. His girlfriend Wendy wears a pink beret.
* Creator/SethMacFarlane seems to love this as evidenced by the characters such as [[WesternAnimation/FamilyGuy Meg and Chris]], [[WesternAnimation/AmericanDad Francine and Stan]] and lastly, [[WesternAnimation/TheClevelandShow Kendra and Lester]] wearing the corresponding colors.
* ''WesternAnimation/MrBogus'' wears a pair of blue shorts, while his less-recurring cousin, Bogetta, wears a pink dress.
* ''WesternAnimation/{{Grojband}}'' has Corey Riffin and his evil older biological sister Trina Riffin.
* {{Inverted|Trope}} in ''WesternAnimation/StevenUniverse'', in which Steven's associated colour is pink, while his friend Connie's associated colour is blue.

[[folder:Real Life]]
* Luvs once marketed pink and blue diapers for girls and boys respectively. The color-coding was more for the parents' convenience; the diapers' design differed between the ones for boys and the ones for girls: there was more absorbent material either in front (for boys) or beneath (for girls) depending on which one they were intended for. They don't do this any more, possibly for the ''manufacturer's'' convenience.
** Huggies Pullups and other absorbent training pants, on the other hand, continue to be colored in pink and blue, because toilet training tends to coincide with the time when children develop gender roles.
** This seems to have been a general thing of the nineties: both Huggies and Pampers (the two biggest brands in the UK) had this through all their range, with only newborn and prem size nappies in unisex green and white. Both dropped it later for single forms packaged in green, yellow or orange (possibly because new materials meant that they no longer have big pads of cotton wadding in them- like ladies' pads, they all now have a gel core).
* OlderThanRadio in RealLife (and well before most other Real Life cited examples of this): The following comes from historian Tamara Plakins Thornton in a book on the history of handwriting instruction. Because eighteenth- and nineteenth-century etiquette recommended teaching different handwriting styles to people of different genders and social ranks (so that one could tell at a glance whether a letter came from a woman, from a member of the lower classes, or from someone socially important), at least one author of handwriting textbooks for the American upper/midle classes color-coded the books by gender. "In 1845[,] writing master James French issued two copybooks, a Gentlemen's Writing Book, bound in blue, and a Ladies ' Writing Book, bound in pink. In the former, French's male students practiced their mercantile running hand [a script style used by 18th- and 19th-century American and English businessmen] ... while their female counterparts rehearsed the ladies' epistolary [a more delicate and ornamented writing style, taught to women and girls of the era instead of the styles considered proper for males] ... " Source: Handwriting in America: A Cultural History by historian Tamara Plakins Thornton, 1998, p. 43. This early American example of Pink Girl Blue Boy is apparently also the sole pre-20th-century example.
* In the Netherlands, it's tradition for parents and older siblings to serve rusk topped with ''muisjes'', little sugar-covered aniseed sprinkles, to visitors, colleagues, and classmates to celebrate a newborn. While initially only available in a pink/white mix, a blue/white mix became available in the early 90s and is now generally used when a boy is born. Since 1938, an orange/white mix has been created for a short period after a royal birth, and with the 'birth' of the new pope in 2005, some catholic institutions handed out rusks topped with yellow/white muisjes, though these were not widely sold in supermarkets, if at all.
* In the 1920s, pink was deemed more appropriate for boys due to its close associations with red. Blue was assigned to girls since it was more “delicate and dainty” and had close ties to the imagery of the Virgin Mary. This practice continued until the 1940s, when the gender colors were reversed and became the stereotypes that we are still familiar with today.
** Before this, babies were usually seen in white or undyed clothes- possibly to symbolise innocence, also possibly because families in those days tended to be large and cloth was more expensive, so parents wanted clothes that would only be worn for a few months to be useful on all their children.
** Just before this trope come into force, Jerome K. Jerome wrote an anguished (but very funny) article of how, now it was suddenly the social convention for babies to actually be brought out in polite company, it had given rise to the social minefield of randomly guessing what pronouns to use for 'baby', and the offence it caused if one got them wrong.
* You can buy pink stocks and grips for a number of guns, including the [[GoodGunsBadGuns AR-15 & AK-47]].
* Many restroom signs are pink for women and blue for men. This may even go as far as the restroom's wall color, and some bathrooms take it even further. Pink and blue toilets for their respective bathrooms, pink or blue sinks, pink or blue dryers/paper towel dispensers (although, thankfully, the paper inside is still white or brown), and yes, even pink or blue liquid soap.
** In some regions of France, the colours never got switched, and pink is still male while light-blue is female. Another thing is that on municipal campsites the restrooms are sometimes only indicated by colour. This troper will never forget that stereotypes vary by country, after he walked into a very busy (blue) women's restroom.
* The cere (the small patch of skin above the beak) of a male parakeet is blue. That of the female is brown.

* In Russian, "pink" is a slang term for lesbians, and "light blue" is a slang term for gay men.
* When the European Starling (''Sturnus vulgaris'') is in adult breeding plumage, the colour at the base of the lower mandible can be used as part of a series of visual cues to estimate the sex of the bird: the male usually has a bluish or bluish-grey base whereas the female usually has a pinkish base.
