Generally, bright colors are used to create a jolly atmosphere or to show a character's extrovert personality. However, sometimes they can hide an unexpected threat. And you may notice it only when it's too late. Why? Probably because you were distracted by all those vivid colors.

Compare LightIsNotGood, contrast DarkIsEvil and EvilIsNotWellLit. Expect it to show up in a StepfordSuburbia, or even more probably in a CrapsaccharineWorld. MonsterClown is a typical character that fits this trope. [[JustForFun/IThoughtItMeant Not related to]] smart and evil characters (you should look at EvilGenius or WickedCultured for this). [[JustForFun/IThoughtItMeant For another kind of]] Bright Is Not Good, see IdiotHero. Supertrope to SicklyGreenGlow, the specific color family of yellowish green that indicates radioactivity, toxicity, acidity, or biohazard; and HollywoodAcid, again, typically a bright green or yellow.

No RealLife examples unless they're scientific ones, please. This is not a trope for petty grievances about a color being associated with a political party or a sport team you don't like.

Oh, and this trope is definitely not about [[Anime/MobileSuitGundam Bright Noah being evil]].



[[folder: Anime & Manga]]
* The last two episodes of ''Anime/NeonGenesisEvangelion'' are a complete psychological breakdown (and recovery!) which feature the most saturated, brightest colors in the series at many parts.
* ''Anime/PuellaMagiMadokaMagica'': A TalkingAnimal, colored white and pink? How dangerous could it be?[[note]][[OffWithHisHead Very]].[[/note]]
** Some of the witches' domains are riots of colour as well, but the one that takes the cake is Charlotte, drawn and coloured like a DisneyAcidSequence.
* ''Anime/TengenToppaGurrenLagann'': Cytomander is an avian beastman with what seems to be peacock DNA. Despite being bright and colorful he is a villain (admittedly a [[SissyVillain sissy]] one) and possibly the most psychotic of the Four Great Generals.
* In ''Anime/KillLaKill'' you have Ragyo, who wears brightly colored clothing so extravagant that Music/LadyGaga would probably tell her to tone it down a bit. She also projects a [[EverythingsBetterWithRainbows rainbow-colored aura]] wherever she goes. And she is TheManBehindTheMan of the anime [[spoiler:later outright BigBad]], one of the most cruel and unforgivable villains in anime ever, and a serious contender for the title of [[AbusiveParents "Worst Anime Mom"]]. The same anime has Nui Harime, who wears a bright pink lolita dress, [[CuteAndPsycho but is just as bad as Ragyo]]. This contrasts the DarkIsNotEvil theme of the protagonist, who is RedAndBlackAndEvilAllOver, without the actual "evil" part.
* ''Anime/PrincessTutu'' has [[RageAgainstTheAuthor Drosselmeyer]]. He wears a long coat of various vivid colors, has big pinkish,red eyes, and long flowing white hair. However, he is a huge sadist that constantly cackles at the heroes' misery and plans on finishing their story with the most tragic ending possible.
* In ''Manga/HotarubiNoTomoruKoroNi'', the fireflies glow quietly and beautifully in the night of the wake. This is not a good omen by any means, as it announces the protagonist being trapped in what seems to be a parallel world where they are the only living humans, and where various things try to kill them.

[[folder: Comic Books]]
* ''Franchise/{{Batman}}'': ComicBook/TheJoker's most famous outfit is purple, along with an orange shirt and a [[color:green: green]] tie. He also has green hair and white skin. Many incarnations add bright red lips to the mix.
* In ''Franchise/GreenLantern'', the Corps with the brightest lights, the Sinestro Corps and Agent Orange, are the most evil. The usual "[[PrimaryColorChampion primary = good]]; [[SecondaryColorNemesis secondary = evil]]" trope doesn't play out here either, with the Sinestro Corps and the Green Lantern Corps being the opposite of what you'd expect from their colors. There's also the Reds, who aren't exactly "good" (though they're more vengeance-oriented berserkers than being "evil" in the traditional sense).
* In ''ComicBook/InjusticeGodsAmongUs'', Regime!Superman retains his trademark blue, red, and yellow costume for the first four volumes after he becomes a murderous, world-conquering KnightTemplar. He pulls an EvilCostumeSwitch at the start of the fifth volume.
* In the ''{{Transformers}}'' franchise, Decepticons often favor dark colors. However, in the Dreamwave Comics G1 series there's a bright orange-and-yellow repaint of Starscream called Sunstorm. He is a totally unhinged [[PoisonousPerson radioactive]] berserker. It was apparently going to be revealed that his madness was due to The Fallen within his mind, but Dreamwave went under before his story could be completed.
* ''ComicBook/CliveBarkersNextTestament'': Wick, the Father of Colors aka God the Father from the Old Testament, is a kaleidoscopic creature whose whole body is covered in vibrant colors. However, [[GodIsEvil he's a malevolent, impulsive, hedonistic deity]] who harbors nothing but ill will for all humanity.

[[folder: Eastern European Animation]]
* ''Animation/NuPogodi'': [[VillainProtagonist Volk]] almost always [[RealMenWearPink wears something]] pink. While not being that bad, he's still a jerk.

[[folder: Fan Works]]
* Played straight with C'ren of Fanfic/OneLessLonelyGurl. She is the BigBad VillainProtagonist MarySue of the story. She has light blonde hair with pink and green streaks, has fair, rosy skin, is a Music/JustinBieber fan, and hates anything dark or gothic. She is the epitome of a prep in FanFic/MyImmortal.

[[folder: Films -- Animated ]]
* Alameda Slim from ''Disney/HomeOnTheRange'', especially in his VillainSong.
* In ''WesternAnimation/ToyStory3'', Woody, Buzz, and the rest are running on a ConveyorBeltOfDoom, hoping to escape the garbage shredders. Rex spots a light at the end of the tunnel, thinking it's the sun (and thus, outside to freedom). Nope, it's the incinerator.
** [[spoiler:Lotso, the movie's BigBad, is a bright pink teddy bear that smells of strawberries and looks unassuming; however he's quite possibly the most evil of all of the bad guys within the franchise.]]
* ''WesternAnimation/TheNightmareBeforeChristmas'': Oogie Boogie whenever he is in the spotlight is very bright and it absolutely fits with his sinister carnival, cheap fun-house, clownish style. The contrast to the gothic colored good monsters is reminiscent of Batman and the ComicBook/TheJoker.
* Tamatoa from ''{{Disney/Moana}}''. He's a gold-encrusted giant crab who lives in a bright cave of treasures and even has a VillainSong called "Shiny" (which is a visual and auditory homage to Music/DavidBowie), who even has his own [[LightEmUp bioluminescent light]]. He's also a human eater, a ''cannibal'', and [[SmugSnake incredibly smug]].

[[folder: Films -- Live-Action ]]
* In ''Film/TronLegacy'', where everyone is ColorCodedForYourConvenience, [[BigBad CLU]] and his {{mooks}} wear black robes with luminescent lines.
** CLU and his army actually use harsher colors (reds and oranges) while everyone else uses light, brilliant shades (blue and white) for their lights. Castor, on the other hand, wears all white.
* In ''Film/XMenFirstClass'', Azazel's skin is vivid red.

[[folder: Folklore]]
* The association of witches with the color black is fairly modern; before that they were most commonly depicted wearing garishly patterned multihued clothing. Almost proto-psychodelic, which may in fact be related to the association of witches with toxic and hallucinogenic plants such as belladonna. See Paul Devereux's ''The Long Trip: The Prehistory of Psychedelia''.
** Garish clothes were a result of association with Gypsies, commonly depicted as wearing outlandish (in the eyes of an average medieval European), multicolored clothes. Also true for Gypsies themselves who were (and sometimes still are) stigmatized as petty thieves and connivers.

[[folder: Literature]]
* [[EldritchAbomination Hastur]] from ''Literature/TheKingInYellow'' and the Franchise/CthulhuMythos.
* In ''Literature/TheLordOfTheRings'', evil wizard Saruman declares himself no longer the White Wizard, but Saruman of the Many Colors.
* From ''Literature/HarryPotter''
** Avada Kedavra, the Killing Curse, is cast as a [[color:lime: vivid green]] light.
** Rita Skeeter always dresses in bright colors, and used to be the biggest bitch in the Potterverse...
** ... until Dolores Umbridge and her obsession with [[color:pink: pink]] came around in ''Literature/OrderOfThePhoenix''.
* In an example that's not ''evil'' but definitely ''dangerous'', ''Literature/CharlieAndTheChocolateFactory'' and its many adaptations present Wonka's Factory as a bright, colorful place, often to the point of AmazingTechnicolorWorld, and its owner/creator's outfit follows suit. But there's a lot of stuff in his factory that ''really'' should not be tampered with or tasted, and not heeding Mr. Wonka's warnings about them seriously results in all manner of crazy disasters. Also, in the 2005 film and 2013 stage musical adaptations, Charlie's environment and costumes therein are outfitted in grays and earth-tones while the four well-off brats come from much more colorful places
* The KnightTemplar Faith Militant of ''Literature/ASongOfIceAndFire'' wear rainbow colored cloaks to symbolize the Seven Gods of the Faith.

[[folder: Live-Action TV]]
* In ''Series/BattlestarGalactica1978'' the Cylons wear (or are made of) bright shiny armor.
* ''Series/DoctorWho'': The New Pardigm Daleks from "Victory of the Daleks", who trade in their predecessors' metallic look for bright colors. The change proved unpopular, however, so we haven't seen much of them since.

[[folder: Roleplay]]
* In ''Roleplay/TheDigimonEpicsCivilWarReboot'', Rhuell Argentum, TheEmperor of the [[TheEmpire Metal Empire]], is a Shoutmon [=EX6=], which is mostly bright, shiny gold.

[[folder: Tabletop Games]]
* The tabletop game ''Polaris'' is built around this trope, as it deals with a perfect civilization under the stars whose destruction is heralded by the appearance of the sun. The dawn's first appearance is described in the gamebook: "Light coming up from the edge of the sky, colors [[color:red: redder]] than stars, new shades that had never been seen, [[color:yellow: yellow]] and [[color:green: green]] and [[color:gold: golden]] through the icicle walls, burning out the stars from the sky, brilliant and impossible and beautiful and alien."
* Followers of Slaanesh (Chaos god of hedonism and excess) in ''TabletopGame/{{Warhammer}}'' and ''TabletopGame/{{Warhammer 40000}}'' are {{Sense Freak}}s who wear hideously garish clothing and choking perfumes at all times, being so blasé it's the only way they can feel anything. One Chaos SpaceMarine Legion devoted to Slaanesh wears [[color:pink: pink]] and black armor for the same reason.
** This is pretty much the principle for all Space Marines, barring a handful that actually care about stealth and wear more subdued colours. But they're still an 8-foot, half tonne killing machine so it seems a bit of a lost cause.
** The Eldar are usually clad in brightly colored armor, but their loyalty is to their own race, and they're willing to let everyone else burn.
** The Mordian Iron Guard Regiment of the Imperial Guard dress in bright colored dress uniforms and look more ready to go on parade than to battle.
** Hilariously {{subverted|Trope}} with Ork Kommandos. They know how to use camouflage, but not all of them quite grasp that the colors should blend in with their surroundings. Sometimes they paint themselves in purple or orange [[InsaneTrollLogic reasoning]] that clashing colors enhance the effect (the enemy can see how well hidden you are from farther away!). The subversion comes in that, since Orks unconsciously warp reality, ''it still works as camouflage.''
* In ''TabletopGame/WerewolfTheApocalypse'', several Zmei (Wyrm dragons) are vividly colored. Rustarin's scales are a shimmering sapphire blue; Trevero's scales are blood red; and Illyana's scales sparkle with all the colors of the rainbow. Despite their colorful appearance, they're also among the most powerful Wyrm minions this side of Malfeas.

[[folder: Video Games]]
* [[MonsterClown Kefka Palazzo]] from ''VideoGame/FinalFantasyVI'' wears an outfit with many vivid colors and different patterns on it. His goal is to destroy the world.
* Ozma from ''VideoGame/FinalFantasyIX'' is a big colourful swirly energy ball thingy. It is what happens when God has an abortion. It's the toughest boss in the game, and, thankfully, optional.
* The entire world of Spira in ''VideoGame/FinalFantasyX'' is, as a rule, vividly colorful and sunny. It's also described by a few characters later in the game as being a "Spiral of Death," and the bright colors are there to distract everyone from their misery.
* The real world in ''[[VideoGame/DmCDevilMayCry Devil May Cry's]]'' [[VideoGame/DmCDevilMayCry reboot]] is gloom and somber while the demon world has extremely vivid colors.
* ''VideoGame/HyperLightDrifter'': Oooooooh yes. The world is replete with [[OrangeAndBlueContrast bright, pinkish reds pale, sickly blues and greens]]. Sounds like a jogging outfit from TheEighties, but instead it dips the world straight into the UncannyValley and emphasizes a sense of [[SceneryGorn worldwide wrongness]].
* The eponymous mask from ''VideoGame/TheLegendOfZeldaMajorasMask'' is exceptionally colorful for being so exceptionally cruel.
** On a meta level, the game has a very colorful, almost saturated color scheme, yet is arguably the scariest entry in the franchise (it's basically about as close to a horror game as an official Zelda title will likely ever get).
* ''VideoGame/PlanetSide'' has the [[MachineCult Vanu Sovereignty]] and the [[LaResistance New Conglomerate]] rebels, which have bright purple/teal and bright blue/yellow armor, respectively. The Sovereignty are fanatically devoted to ([[UnwillingRoboticisation forcibly]]) "uplifting" humanity. The Conglomerate are devoted to personal freedom, [[MegaCorp corporate profits]], [[PrivatelyOwnedSociety libertarianism]], and laissez-faire capitalism.
* ''VideoGame/WorldOfWarcraft'' has the Scarlet Crusade who are all armored and red all over. They are an order dedicated in eradicating the Undead Scourge, a noble intent, but their methods involve killing or torturing anyone suspected to be part of the undead or infected by the plague. Which is anyone not part of the order. [[spoiler:It doesn't help that one of their leaders is actually a Dreadlord.]]
* The resident villainous group of ''VideoGame/PokemonXAndY'', Team Flare, dress in eye-searingly bright orange suits that they consider high fashion, but several [=NPCs=] note to be [[FashionVictimVillain horribly tacky]].
* In ''VideoGame/{{Evolve}}'', the monster adaptations are brightly colored and just as lethal as the originals.
* [[VideoGame/FiveNightsAtFreddys Freddy Fazbear's Pizza]] is full of balloons, streamers, children's drawings, and candy-colored animatronics. And death.

[[folder: Web Comics]]
* ''{{Webcomic/Roommates}}'' is generally black and white but from the occasional color illustration TheFairFolk like bright colors a lot, like the MonsterRoommate is fond of golds, his mother (and CardCarryingVillain) whites and pale blues, his sister bright purples etc., also several resident [[AxCrazy psychos]] like bright reds way too much.
* Posey from ''Webcomic/TheSanityCircus'' dresses in cheery red colours and, in the early chapters, is often set against bright bloom backgrounds. She is a fear-eating EldritchAbomination in the form of a small girl.

[[folder: Western Animation]]
* The Gigglepies and their CrapsaccharineWorld from ''WesternAnimation/TheFairlyOddparents''.
* From the [[Franchise/TransformersGeneration1 the good ol' 80s series and comics]] through ''[[Anime/TransformersCybertron Cybertron]],'' Starscream of ''[[{{Franchise.Transformers}} Transformers]]'' had a red, white, and blue color palette, the same as BigGood Optimus Prime, and generally brighter and friendlier colors than the darker-colored Decepticons. He really stands out amongst the Seekers, his PaletteSwap buddies from the original series. You've got Starscream's bright and friendly colors next to Skywarp's black, Thundercracker's dark blue, and the mass-produced {{Mooks}}' light purple. Of course, he is, well, TheStarscream.
* Giffany from the ''WesternAnimation/GravityFalls'' episode "Soos and the Real Girl" is an {{Animesque}} character from a dating sim whose color scheme is primarily bright pink. She also turns out to be [[ClingyJealousGirl incredibly possessive]], to [[{{Yandere}} psychotic extremes]].

[[folder: Real Life]]
* A sudden, bright flash/lighting up of the horizon or even worse, the entire sky ''accompanied with sudden heat'' can only mean one of three things: [[UsefulNotes/NuclearWeapons a nuclear bomb has just exploded somewhere nearby]], [[ColonyDrop an asteroid or comet has made entry into the Earth's atmosphere]], or [[ApocalypseHow a gamma ray burst has hit the earth]]. The flash from any of these is powerful enough to blind you and its heat can do anything from cremate you alive to give you a slight sunburn, depending on what happened and how far you were from it. A distant flash on the horizon ''not'' accompanied by sudden heat can be distant lightning or fireworks (or in some locales an aurora), but a flash with heat ''always'' means "something very, very bad is happening and whatever the hell you do [[EyeScream don't look at it!]]"
* [[http://en.wikipedia.org/wiki/Aposematism Aposematism]] includes the use of vivid colors by animals as a warning sign against predators.
** The most famous example is the [[http://en.wikipedia.org/wiki/Poison_dart_frog poison dart frog]].
** The Monarch Butterfly, which is toxic to birds...and is actually mimicking the Viceroy Butterfly, which is ''not'' poisonous, but [[ItTastesLikeFeet tastes like aspirin]].[[note]][[NotHyperbole No, really.]] The caterpillars feed on willow trees and store salicylic acid, an important, but bitter, active ingredient in aspirin.[[/note]]
** Some animals have bright colors despite not actually being poisonous to fool potential predators. Unfortunately for them, not all predators are that easily fooled. It's pretty risky to draw attention to yourself via bright colors when you don't actually have anything protecting you.
* The [[http://en.wikipedia.org/wiki/Mantis_shrimp mantis shrimp]]. It's brightly colored, probably much more colorful than our eyes and brains can handle - especially since it has 16 varieties of cone receptors in its eyes (compared to the 3 varietes we have), allowing it to see an almost impossibly wide light spectrum. It also looks really cute, in an [[EldritchAbomination alien sort of way]]. It also [[OmnicidalManiac brutally, happily murders everything around it]] with its claws, delivering [[MegatonPunch dismembering supersonic punches]] which deal massive damage even when they miss, because the water around the claw starts boiling due to friction caused by the speed of these punches. It's strong enough to punch through aquarium glass (which, coupled with the aforementioned bloodlust, makes it a poor choice for most aquariums) and injure human beings, and has earned an affectionate nickname ''thumb splitter'', since that's what will happen if you try to touch it. Oh, and those claws? They're so tough that scientists would love to replicate their structure, in case it can be reproduced in human scale and used in the military.
* Chemical hazard labels have bright backgrounds to be easily spotted.
* Many chemical substances present themselves in colorful crystals, or burn with pretty colors. Many are explosive/toxic/otherwise dangerous.
* An astronomy example: the brighter or more vivid the star's color, the worse it is for evolving life. Bright blue stars are the worst for evolving life. Red stars are bad, too. Red dwarfs are too small and cold, red giants too bright and unstable. Mediocre whitish or yellowish stars (yellow-white F class, the Sun's G class or the yellower-than-Sun K class) are the best for Earthlike planets. And, finally, ZigZagged with brown dwarfs, which aren't candidates for life-bearing planets at all. While the name doesn't sound very bright and therefore the trope seems to be averted, they are actually deep glowing red and worse (colder) than red dwarfs, playing it straight.
* Fire. As the temperature grows higher (and thus more dangerous), the color of the flame shifts from red, to pink, to bright blue. This is common knowledge among fire-fighters.
* Many animals react violently or panic at the sight of the color red, because they take it as a sign that one of their companions has been wounded and is bleeding heavily.
* The colors of certain [[EverythingsBetterWithDinosaurs dinosaurs]] have been figured out thanks to microscopic pigment cells in the fossils of their plumage. Most of them had fairly dark colors. The brightest of them? ''[[https://en.wikipedia.org/wiki/Sinornithosaurus Sinornithosaurus]]'', a [[DeathFromAbove hawk-like predator]] that was [[RedAndBlackAndEvilAllOver decked out in red, grey, yellow and black]]. Ironically, its colors are thought to have been used for [[ChameleonCamouflage forest camouflage]].
* For this very reason, strong lamps have been used in interrogation rooms to extract confessions from criminals or hostile agents.
