History RedOniBlueOni / LiveActionTv

* {{Series/Frasier}} (red) and his younger brother Niles (blue). Note that this does not mean Niles is any less neurotic or eccentric than Frasier, just that he has a far milder temper. Their demeanors fit the mold (Frasier's brand of conceited pompousness is overbearing and HotBlooded while Niles' is fussy and sharp-tongued) and Niles is more down-to-earth by comparison whenever Frasier gets caught up in his ridiculously over-emotional trains of thought, irrational schemes and obsessions, and explosions of anger or vengeance.

** The charmed ones (The three Halliwell sisters): In the early seasons there was the oldest sister Prue (Generally blue as she was the most mature and responsible and [[PromotedToParent often acted as a mother figure to her younger sisters Piper and Phoebe]]. However, she was also short-tempered and high strung at times and could easily turn red if provoked, especially when Piper and Phoebe were in danger.), the middle sister Piper (Initially the bluest of the sisters: Meek, timid, TheQuietOne, and often played mediater to Prue and Phoebe. [[TookALevelInBadass However, she became much more red in later seasons as she grew more assertive, bossy, and temperamental.]]), while impulsive, free-spirited youngest sister Phoebe was a definite red. In later seasons after [[spoiler: [[RealLifeWritesThePlot Prue's death]]]], the Halliwell's newly discovered half sister Paige is the blue to Piper and Phoebe's red.

* ''Series/KenanAndKel'': [[{{Cloudcuckoolander}} Kel]] is the Red Oni, being neurotic, energetic, and stupid with a [[TrademarkFavoriteDrink weird addiction to orange soda]], whereas [[OnlySaneMan Kenan]] is the Blue Oni, being rational and smart in comparison.

* ''{{Series/Legion|2017}}'': David Haller is hot-headed and is determined to kill Amahl Farouk, whereas Charles Xavier is level-headed and wants to try diplomacy first.
-->'''David''': We need to focus. Killing Farouk. A plan.\\

* In the French series ''[[Series/LesPetitsMeurtresDAgathaChristie Les Petits Meurtres d'Agatha Christie]]'', reporter Alice Avril is the Red to Commissaire Laurence's Blue. Their costumes even lampshade this; Avril wears a red leather jacket and Laurence's suit is usually blue.

* ''Series/KenanAndKel'': [[{{Cloudcuckoolander}} Kel]] is the Red Oni, being neurotic, energetic, quite stupid and has a [[TrademarkFavoriteDrink weird addiction to orange soda]], whereas [[OnlySaneMan Kenan]] is the Blue Oni, being rational and smart.

* ''Series/StepByStep'': The rebellious tomboy Al and the ditzy girly-girl Karen are two different kinds of red; the intellectual feminist Dana is blue.

* ''Series/UltramanGaia'' has [[TheHero Takayama Gamu]] (Gaia, red Ultraman) an idealist who believes that the Gaia's purpose is to save Earth and humanity. And [[{{Deuteragonist}} Fujimiya Hiroya]] (Agul, blue Ultraman), who is more focus on defeating monsters and more interested in protecting just the planet itself, even at the expense of humanity. Fujimiya eventually TookaLevelInKindness, but remains as more cool head.

* In ''Series/{{Starsky and Hutch}}'', the street-smart Starsky (red) and the book-smart Hutch (blue).

** According to Shatner's autobiography, one problem they had with the original pilot, The Cage, is that Captain Pike and Mr. Spock were too similar. If you were going to have an unemotional Mr. Spock, then the captain needed to be very emotional so that they could play off of each other, and that's how Shatner played him. Also, the show originally was meant to be Kirk and Spock, and the [=Kirk/Spock/McCoy=] trio developed on its own. (Note that only Shatner and Nimoy were given star billing in Season 1; it wasn't until Season 2 that "{{And|Starring}} [=DeForest=] Kelley as Doctor [=McCoy=]" was added to the opening sequence.)

* A Creator/DisneyChannel movie called "Stepsister from the Planet Weird" had this for the two families: the down-to-earth Earthlings were blue while the literally air-headed (they're bubbles) and overly emotional aliens were pink/orange. Naturally, their wedding theme was purple.

* ''Series/TheGoldbergs'': The Goldberg Family served as the loud-mouthed and dysfunctional, Red Oni's to the soft-spoken and well-behaved Kremp Family who were the Blue Oni's.

** The red of the mischievous and bumbling Second Doctor to the blue of the intellectual Zoe

* ''Grange Hill'' has several examples: Tucker Jenkins is red to Alan Humphries and Benny Green's blue. Mrs McClusky is blue to both Mr Keating's and then Mr Bronson's red. Gonch Gardner was red to Hollo's blue. Pogo Patterson was red to Duane Orpington's and Stewpot Stewart's blue. Then among the girls, Trisha Yates was red to Cathy Hargreaves' blue, Suzanne Ross was red to Claire Scott's blue and Annette Firman was red to Fay Lucas' blue. Although all three of those female blue onis did go off the rails at some point.

** [[TheCaptain Mal]] and [[TheMedic Simon]] are set up at the start to look like Red Oni and Blue Oni; Simon's even set up to look like a villainous Blue Oni. Then the truth is revealed and from that point on, it's very clear that while they superficially look like an ideal RedOniBlueOni example, they're actually a case of NotSoDifferent, as Simon is every bit as passionate and willing to break the rules and law as Mal. As it turns out, [[HiddenDepths he's even got a better talent for crime than Mal]] -- at least, when it involves a subject he's familiar with.

** According to Shatner's autobiography, one problem they had with the original pilot, The Cage, is that Captain Pike and Mr. Spock were too similar. If you were going to have an unemotional Mr. Spock, then the captain needed to be very emotional so that they could play off of each other, and that's how Shatner played him. Also, the show originally was meant to be Kirk and Spock, and the [=Kirk/Spock/McCoy=] trio developed on its own. (Note that only Shatner and Nimoy have "I get what he gets" clauses in their contracts.)

*** Mirrored by the colors -- Ex-Aid's main form is pink, while Brave's is blue.

** It's the other way around with the Fifth Doctor. The Fifth Doctor is the calm and collected blue to the red of the snarky Tegan.

** Both shows have this with the vampires Spike and Angel. The former being Red, the latter being blue. Especially in Season Five of ''Angel''.

** Faith and Buffy after Kendra dies. And maybe Willow and Tara in season six.

** Felicia "Snoop" Pearson and Chris Partlow, the enforcers for up-and-coming drug dealer Marlo Stanfield in Season Three, also form this dynamic. However, the one time Chris truly loses it, even Snoop is amazed.

* A nice example in ''Series/HomicideLifeOnTheStreet'' with the duo Bayliss/Pembleton. Bayliss is a somewhat {{Emo}} young man who is tragically unable to keep emotionally distant from his job and is given to outbursts of violence, but is also caring and sensitive. Pembleton is an older, smarter, educated, cold, and occasionally smug professional.
* At the end of the pilot of ''{{Series/Leverage}}'', you see a group shot in which the two most hot-headed and aggressive of the crew (Nate and Eliot) have on red ties, and the two most calm and collected members of the team (Sophie and Hardison) are wearing blue. Of course, Parker, being the [[HeroicComedicSociopath resident sociopath]], has no color scheme.
* ''Series/JeevesAndWooster'' -- Jeeves is the level head (Blue) to Bertie's naïve optimism (Red).
* ''Series/SaturdayNightLive'' gave us loud, cocky Wayne Campbell (red) and shy, nerdy Garth Algar (blue).
* ''Series/KeenEddie'': Eddie Arlette and Monty Pippin take turns with who is what. In their work, Monty is blue and Eddie is red, while in their private lives, it's the other way around.
* ''Series/{{Community}}'':
** HeterosexualLifePartners Troy and Abed. Troy, a [[LargeHam highly expressive]] LovableJock, is the Red Oni to Abed, a [[TheStoic stoic]], [[AmbiguousDisorder undiagnosable]] nerd.
** Annie and Jeff. She's a GoGetterGirl full of drive and can-do spirit while he's a cool-headed (or, at least he wants everyone to think he is) BrilliantButLazy DeadpanSnarker.
* ''Series/TeenWolf'': Scott and Stiles fit this trope to a T, with Scott as the Red Oni and Stiles as the Blue Oni. Scott is more impulsive, passionate and reckless; these traits were magnified after he became a werewolf. Stiles is the Blue Oni; he is more logical, calm and composed and doesn't get as emotional and hot headed as Scott.
* ''Series/TheVampireDiaries'' has a rather unusual example with the brothers Stefan and Damon, with the younger brother Stefan playing a heroic Blue to his older brother's Red. Damon is impulsive and passionate and tends to flip between anti-hero and villain on a whim, while Stefan is usually measured and controlled.
** Show also has [[TheGenericGuy Matt]] and [[JerkWithAHeartOfGold Tyler]].
** Not to mention HeterosexualLifePartners [[TeamDad Alaric]] and [[SociopathicHero Damon]].
* In ''Series/{{Starsky and Hutch}}'', the street-smart Starsky (red) and the book-smart Hutch (blue).
* ''Series/{{Dexter}}'': Dexter himself is blue and each of the main killers of each season are red.
** Also, his sister Deb might qualify as red.

* ''Series/{{Torchwood}}'' currently has emotional, impulsive Gwen Cooper and cool, almost perpetually blasé Captain Jack Harkness. In past seasons, hotheaded, profane Owen Harper and reserved, polite Ianto Jones played Red and Blue respectively when interacting with pretty much ''anyone'' else.
* {{Series/Frasier}} (red) and his younger brother Niles (blue). Note that this does not mean Niles is any less neurotic or eccentric than Frasier, just that he has a far milder temper. Their demeanors fit the mold (Frasier's brand of conceited pompousness is overbearing and HotBlooded while Niles' is fussy and sharp-tongued) and Niles is more down-to-earth by comparison whenever Frasier gets caught up in his ridiculously over-emotional trains of thought, irrational schemes and obsessions, and explosions of anger or vengeance.
* ''Series/TheNanny'': Fran Fine (appropriately called "The LadyInRed" in the theme song) and Maxwell Sheffield.
* ''Series/{{Psych}}'': Impulsive, intuitive Shawn (red) and thoughtful, cautious Gus (blue).
* ''Series/BreakingBad'' plays around with this. For starters, Jesse Pinkman and Walt White epitomize recklessness (youth) vs. calculation (experience). Hank and Walt similarly reflect this, mainly with the former's direct, almost obnoxious way of dealing with his family and job. However, Jesse plays Blue when dealing with his less smart cohorts Badger and Skinny Pete. Walt and [[spoiler:Gus Fring]] also flip this around: the first acts more out of emotion and concern for his family and (sometimes) Jesse. The latter, who has no emotional attachments the audience knows of (or at least living ones), conducts business the way only a cold-blooded monster would, taking extreme caution to keep his respectable businessman facade while not minding his underlings' (or anyone else's) deaths to keep his drug distribution outfit operating.
* ''Series/TheFreshPrinceOfBelAir'' has [[TheDanza Will Smith]] and [[BlackAndNerdy Carlton Banks]].
* On ''Series/GilmoreGirls'', there's the pro/con list making Rory and the frustrated Paris.
** And, of course, the titular mother and daughter. That's right, Rory is ''both.''
** Rory is also the blue oni to her BFF [[GenkiGirl Lane]].
** [[ThoseTwoGuys Zach and Brian]] are Red and Blue, respectively.
* ''Series/AmericasNextTopModel'', full stop. At least one model per cycle borders on absolute Red; at least one other borders on absolute Blue; and everyone else falls in between, depending on whom they're compared to.
** The two Jays are a [[IncrediblyLamePun straighter]] example. J. Alexander (Miss Jay) is the FunPersonified EccentricMentor while Jay Manuel (Mister Jay) is [[SternTeacher the more serious and level-headed one]].
* The two generation of Scott brothers from ''Series/OneTreeHill''.
** Basketball-loving [[TookALevelInKindness former]] JerkJock Nathan is the red, while CulturedBadass Lucas is the blue.
** Their father Dan is the {{Jerkass}} red while their CoolUncle Keith is the obvious blue.
* The red and blue [[AlternateUniverse universes]] from ''Series/{{Fringe}}''. The people from the red universe are DarkerAndEdgier compared to their counterparts from the blue universe, who are the main characters of the series. The Bishops tend to be an exception in many ways, [[spoiler:which makes particular sense in Peter's case since he's originally from the red universe anyway]].
* ''Series/UltramanGaia'' has [[TheHero Takayama Gamu]] (Gaia, red Ultraman) an idealist who believes that the Gaia's purpose is to save Earth and humanity. And [[{{Deuteragonist}} Fujimiya Hiroya]] (Agul, blue Ultraman), who is more focus on defeating monsters and more interested in protecting just the planet itself, even at the expense of humanity. Fujimiya eventually TookaLevelInKindness, but remains as more cool head.
* In ''Series/ModernFamily'', it's astoundingly able to pull off a RedOniBlueOni dynamic with pretty much any pair-up between the three main families. Within the parents there are Claire and Phil, Gloria and Jay, and Cameron and Mitchell. With the kids, Haley and Alex along with Luke and Manny. The pairs and even roles get switched around constantly.
* ''Series/TheInspectorLynleyMysteries'': Barbara Havers is red, Thomas Lynley is blue. However, as is this show's habit, the reality is slightly more complex: Havers is certainly more fiery and hotheaded in daily life, but she is generally the cool, collected one in a crisis, whereas Lynley is usually the more rational and pragmatic one, but tends to panic when the shit hits the fan. Also, Lynley is more likely to fly off the handle at suspects, whereas Havers is more likely to react with TranquilFury.
* ''Series/AustinAndAlly'', impulsive Austin (red), and level-headed Ally (blue).
* In ''{{Series/Bones}}'', the entire character dynamic is based off of Bones being ''everyone's'' Blue Oni. The most obvious Red is Agent Booth, though Angela also fits the description rather well.
* Lois and Hal in ''Series/{{Malcolm in the Middle}}'' go both ways in different aspects: Red Lois (temperamental, loud, scary, flying off the handle at the kids) vs. Blue Hal (easygoing Dad, the quiet one); and Blue Lois (more pragmatic, down to Earth, runs a tight ship) vs. Red Hal (impulsive, can be irresponsible). In the balance Lois is overall red and Hal is overall blue though.
* ''Series/{{The Big Bang Theory}}'': Sheldon is red to Leonard's blue; Howard is red to Raj's blue.
* ''Series/That70sShow'':
** Jackie is red to Donna's blue; Kelso is also red to Eric's blue. Donna and Eric were one time snarkily nicknamed "Mom and Dad" among the group by Kelso.
** Hyde's bluer than all of them though. Jackie was slightly the blue one to Kelso's red when they were a couple, both being fairly red in general though; the red Jackie/blue Hyde contrast was striking when those two became a couple.
** Donna is mostly blue, but she also has some red qualities, as she can be hot-tempered and want to break rules and traditions. Hyde is also rebellious, despite being mostly blue, while Kelso and Jackie aren't, despite being mostly red.
** Red and Kitty could go either way with each other: red Red (temperamental, is gonna put a foot in someone's ass) vs. blue Kitty (generally a calming force and more easygoing, particularly with Eric); but also red Kitty (can get sloppy drunk and silly, sometimes snaps and loses temper herself) vs. blue Red ("calm down Kitty", "you've had enough Kitty"). Probably made them a good stable married couple, as they could play either to balance out the other that way as needed. Red could also be quite a DeadpanSnarker and occasionally a softspoken badass (watch out then), both generally blue traits.
** Bob was definitely red (impulsive, outgoing, loud) to Midge's calm and cool blue.
* ''Series/{{Roseanne}}'': Becky and Mark were red; Darlene and David were rebellious, but were still mostly blue.
* ''Series/StepByStep'': The rebellious tomboy Al and the ditzy girly-girl Karen are two different kinds of red; the intellectual feminist Dana is blue.
* ''Series/{{Rome}}'': Pullo is red, Vorenus is blue. Occasionally subverted, particularly when things go bad for Vorenus
* {{Series/Power}}: James and Tommy run a major drug gang in New York. James is calm, collected, and business minded, running the night club they use to launder their money. Tommy is impulsive and HotBlooded, and primarily handles running their street crews.
* ''Series/TheManFromUNCLE'' has casually debonair American agent Napoleon Solo as Red Oni to his coolly intellectual Russian partner, Illya Kuryakin's Blue Oni. Slightly ironic in terms of political "colours" of the day, as Kuryakin was apparently a Soviet national living in America and hence considered a "Red" during the Cold War of the 1960's.
* ''Series/JessicaJones2015'': Jessica is the brash and short-tempered Red Oni to both Luke's and Trish's calmer and more even-tempered Blue Onis.
* The two popular talk shows ''Series/TheJerrySpringerShow'' and ''Series/TheJeremyKyleShow'' definitely serve this trope well. (Red) Jerry Springer's audiences (and guests) are untamed and free to express opinion '''regardless''' of the consequences. While (Blue) Jeremy Kyle's talk show is strict, considerate and casts judgement with sincere shunning and less physical abuse.
* ''Series/TheGoldbergs'': The Goldberg Family served as the loud-mouthed and dysfunctional, Red Oni's to the soft-spoken and well-behaved Kremp Family who were the Blue Oni's.
* ''Series/ParksAndRecreation'': [[GenkiGirl Leslie]], [[FunPersonified Andy]], [[SmallNameBigEgo Tom]], [[ThePollyanna Chris]], and [[SassyBlackWoman Donna]] are red while [[OnlySaneWoman Ann]], [[TheComicallySerious Ron, Ben]], [[DeadpanSnarker April]], and [[ButtMonkey Jerry]] are blue.
* ''Series/TheDakotas'': Deputy J.D. Smith, a reformed hired gun and a textbook {{Lancer}}, is the Red Oni to his by-the-book Blue Oni boss, Marshal Frank Ragan. Smith tends to bend the rules and do things Ragan's not exactly willing to do, forcing Ragan to remind him he's a lawman now and can't always solve everything by shooting someone. In later episodes, Smith and Ragan consciously use this dynamic (unbeknownst to the other two deputies as well as the outlaws) to put one over on someone they're trying to bring to justice.

* ''Series/DeadToMe'' has the hot-headed and short-tempered Jen (Red) and the optimistic, empathetic Judy (Blue).

* Played with in ''Series/DrakeAndJosh''. Drake does things without thinking (red), but is cool, calm, and collected (blue), while Josh plans things (blue), but is clumsy, overemotional, and often loud (red).
* ''Series/GameOfThrones'':
** The deathly cold White Walkers and the fire-breathing dragons and fire-themed Lord of Light.
** The honorable Starks and the pragmatic Lannisters.
** TheStoic, grim, peace-loving, modest, even-tempered Blue Ned Stark and the boisterous, hedonistic, ''very'' hot-blooded, impulsive Red Robert Baratheon, who is like this by nature well into his old age.
** Arya is the gutsy, extroverted, outgoing, hot-tempered red to Gendry's calmer, introverted, quieter blue in Season 2 and 3. (Ironically inverting the dynamic in their father's friendship as Ned was blue to Robert's red). She gets colder and more emotionless in later seasons.
** The TomboyAndGirlyGirl sisters Arya and Sansa Stark.
** Chaotic Littlefinger and lawful Varys get a widescreen MirroredConfrontationShot in "Fire and Blood" to illustrate their OrderVersusChaos rivalry.
*** Though arguably they're both blue oni, just with different goals; whomever they're helping/pretending to help is their red oni du jour. (Varys blues to the reds of Tyrion and Daenerys, Baelish to Sansa and Cersei. Both bring out Ned's rare red moments.)
** Brandon was the reckless, HotBlooded Red to his brother Ned's patient, soft-spoken Blue.
** Kinda, with House Clegane. Sandor isn't exactly serene and emotionless, but he's much more stoic and in control of himself than Gregor. Emphasised by their fight at the Hand's Tourney, when King Robert orders them to stop, Sandor immediately drops to one knee (handily ducking Gregor's swing), while Gregor tosses aside his sword and storms off in a rage.
** Joffrey serves as the violent, impulsive, sadistic Red Oni to the calm and intellectual Tyrion, the cold and calculating Tywin, and the meek, soft-spoken Tommen.
** Tyrion is the blue to Jaime's more hotheaded red.
* ''Grange Hill'' has several examples: Tucker Jenkins is red to Alan Humphries and Benny Green's blue. Mrs McClusky is blue to both Mr Keating's and then Mr Bronson's red. Gonch Gardner was red to Hollo's blue. Pogo Patterson was red to Duane Orpington's and Stewpot Stewart's blue. Then among the girls, Trisha Yates was red to Cathy Hargreaves' blue, Suzanne Ross was red to Claire Scott's blue and Annette Firman was red to Fay Lucas' blue. Although all three of those female blue onis did go off the rails at some point.

** The Daleks are red to the Cybermen's blue

* ''Series/TheSecretCircle''
** Cassie (Red) and Diana (Blue)
** Cassie (Blue) and Faye (Red)
** Diana (Blue) and Faye (Red)
** Faye (Red) and Melissa (Blue)
** Adam (Blue) and Jake (Red)
* Although Justin and Alex, from ''Series/{{Wizards of Waverly Place}}'', are both sarcastic and, to an extent, {{Deadpan Snarker}}s, they have really different personalities. While Alex is witty, prankish, and lazy, never taking anything seriously (represented by red), her older brother, Justin, is responsible, much more mature, studious, and collected (represented by blue).
** The interesting thing is that in their wizard competition, they reversed the associated elemental roles, with Justin showing more of an affinity for fire, while Alex tended to use water.
* Many ''Franchise/SuperSentai'' and ''Franchise/PowerRangers'' series have the [[TheHero Red Ranger]] as a Red Oni, and several have the Blue Ranger as something of a Blue Oni. Few have their relationship as a major theme, though.
** ''Series/TokusouSentaiDekaranger'' has Ban Akaza, the Red Ranger/Oni who is chaotic but friendly, and Hoji Tomasu, the Blue Ranger/Oni who is professional but arrogant. The American version, ''Series/PowerRangersSPD'', does the same with Jack Landors and Sky Tate, although Jack does not embody DumbIsGood to the same extent as Ban.
** ''Series/ChoushinseiFlashman'' reverses colors with its duo: Jin, the Red Flash, is the more sensible and mellow Blue Oni, whereas Dai, the Green Flash, is the strong, arrogant, and frightening Red Oni.
** Gai and Ryuu of ''Series/ChoujinSentaiJetman'', though their colors are reversed: Ryuu (TheHero) is the Blue Oni but wears red, and Gai (TheLancer) is the Red Oni but wears black.
** Another Example is ''Series/SamuraiSentaiShinkenger'', Same as Jetman and Zyuranger, colors are reversed: Takeru (TheLeader) is the Blue Oni who is more sensible and cautious yet he always calculate when it comes to decision and planning but wears red with fire element and Ryuunosuke (TheLancer) is the Red Oni who is impulsive and emotional and most likely to jump into conclusion instinctually and bring the situation livelier for fun but wears blue with water element.
** ''Series/MightyMorphinPowerRangers'' fit the trope to an extent -- the Red Ranger was the confident, extremely physical leader of the band while the Blue Ranger was the intellectual brainiac of the bunch.
*** Of course ''Series/KyoryuSentaiZyuranger'' is rather different from its American adaptation -- Tyrannoranger Geki is calm and smart by default, as Triceraranger Dan is dumb, brash, and wanting to rush into a fight.
** Whenever the ''Power Rangers'' writers get lazy and make the Rangers {{exp|y}}ies of ''Sentai'', the theme shows up more. Often ''Sentai'' will have the HotBlooded Red who lives by DontThinkFeel and the calm expert Blue. ''Power Rangers'' tones down the loud screaminess of the Reds but falls back on RookieRedRanger to the point that the dynamic is the same: a Red who's ''winging it'' and an expert Blue, who's actually more likely to be annoyed with Red than in ''Sentai''. It's worse when the Rookie Red is given formal authority. (See, it's known that Red is "always" the leader, but half the time, "Leader" seems to mean "Red stands in the center for the SuperSentaiStance because it's habit." Nobody ever actually said [[Series/PowerRangersLostGalaxy Leo]] or [[Series/PowerRangersOperationOverdrive Mack]] were in charge of anything; but in ''SPD'' and ''Wild Force'', that's ''not'' the case, and the guy who doesn't know what he's doing outranking the one who does is a way to keep the friction going for quite some time.)
** ''Series/KaizokuSentaiGokaiger'' has [[TheGoodCaptain Captain]] [[AwesomeMcCoolname Marvelous]] as the Red Oni, wearing red. However, he has ''two'' Blue Oni counterparts, in the forms of [[TheStoic Joe]] and Basco.

* Jack O'Neill and Dr Daniel Jackson from ''Series/StargateSG1'' could fit into this trope as many of the earlier episodes' conflict came from O'Neill's emotional pragmatism conflicting with Daniel's intellectual desire to study and understand various things. Interestingly, this is often reversed in later seasons -- Jack descends into rational, Black-Ops mindset as Daniel plays up his I-empathize-with-everyone side.
** Ronon and Teal'c have this kind of relationship in the ''Series/StargateAtlantis'' episode "Midway". Ronon being the aggressive and wild Red Oni and Teal'c being the calm and cultured Blue Oni. And both being TheBigGuy of their respective show.
** Rodney [=McKay=] is Red Oni to almost any other scientist that appears on the show, notably Zelenka, Beckett, and [[spoiler: Beckett's replacement and [=McKay=]'s love interest, Dr. Keller.]]
*** Unusual in that Rodney is usually smarter than his Blue Oni, which makes up for his often-times unscientific professionalism. When he plays opposite Samantha Carter, who is the only scientist in the SGC that he accepts as being better than him, [=McKay=] plays a bit more traditional Red Oni.
* On ''Series/JudgeJudy'', a calm woman with dyed-blue hair sued an angry woman with dyed-red hair.
* ''Series/{{Firefly}}'' loves playing with this trope and stretching the boundaries of it as far as they can go, sometimes with mind-bending results.
** [[TheCaptain Mal]] and [[TheMedic Simon]] are set up at the start to look like Red Oni and Blue Oni; Simon's even set up to look like a villainous Blue Oni. Then the truth is revealed and from that point on, it's very clear that while they superficially look like an ideal RedOniBlueOni example, they're actually a case of NotSoDifferent, as Simon is every bit as passionate and willing to break the rules and law as Mal. As it turns out, [[HiddenDepths he's even got a better talent for crime than Mal]] -- at least, when it involves a subject he's familiar with.
** Jayne and Simon have an equally interesting dynamic. Their RedOniBlueOni relationship is deliberately used to play them against each other in almost every scene they share. However, who is Red and Blue actually changes depending on the situation. For all of Jayne's [[HotBlooded hot-headed]], uncultured nature, he's also a very level-headed CombatPragmatist with sometimes surprisingly accurate assessments of people and situations. This is often used to compare and contrast with Simon's cultured intellectualism that only superficially masks his deeper passion and idealism.
** In a similar sense to Simon and Jayne, Jayne's pragmatism is sometimes used to play villainous Blue Oni against Mal's heroic Red, especially with regards to the issue of keeping Simon and River on [[CoolStarship the boat]]. No-one can deny the sheer logic of Jayne's attitude, but Mal's far too compassionate to be swayed by it.
*** And yet at the same time, Jayne's immediate recourse to violence, his impulsive nature with money or loyalty, and his immediate, snap dislike of Simon (contributing to his attempt to get him off [[CoolStarship the boat]] ) makes him a pretty good candidate for Red. They play the roles very well, but the Red/Blue divide mostly seems to depend either on the issue at hand, or which characters eyes you're seeing it through.
** Mal's most obvious Blue Oni counterpart is Zoe, who is also a Blue Oni to her husband's Red Oni.
** There's also one going between Simon (Blue Oni) and Kaylee (Red Oni).
** To an extent, this also applies to Mal and Shepherd Book. Although Book has a somewhat rough, earthy nature akin to a red oni, he is also a very intellectual, spiritual, and cultured individual. Besides that, there's his heavily hinted past with the Alliance, which is about as blue an organization as you can find.

* Peter and Nathan Petrelli from ''Series/{{Heroes}}''. Nathan takes the role of the AloofBigBrother while Peter is the younger, emotional, and, unfortunately for many, an IdiotHero. Also, Peter and Sylar, according to how their powers work (Peter's is empathy, Sylar's is intuitive aptitude). However, in Season 3, [[spoiler:Peter absorbs Sylar's ability, making him have the ''hunger'', and Sylar has had Peter's ability all along]]. Also deconstructed in a future episode, where Peter summons fire while Sylar summons ice. It makes even more sense since [[spoiler:Peter and Sylar are revealed to be brothers.]]
** Except [[spoiler: it's later revealed that was [[AssPull just a lie]] and they are, in fact, not brothers]].
** Also, if you compare the heroes with their future selves, who are all apparently ''badass''. [[spoiler:It's inverted in the case of ''Sylar'', where he moved into Claire's home, calls himself Gabriel (his real name) and is much nicer than his present self. He even has a ''son'' named ''Noah''.]]
** Inverted in the case of the siblings [[spoiler:Meredith and Flint]]. Meredith has the red fire, but she is much calmer and more level-headed than her younger brother, who's about as bright as a flea but has the blue fire. However, since Meredith is on the side of good, she possesses a genuinely warm (pardon the joke) and caring personality for her family while her brother is ruthless and even killed a woman with his powers.
** Also, in an early first-season episode, Mohinder and Sylar are speaking about Mohinder's father (who was actually murdered by Sylar, unknown to Mohinder). At first, both are lit by a blue-green light, but when the murder comes up, Sylar turns away from Mohinder and smirks, and his face is lit in a red light. Mohinder's still in the blue light.
* This dynamic plays out with several characters in ''Series/TheWire'':
** Jimmy [=McNulty=] and Bunk Moreland possess this dynamic: [=McNulty=]'s a free-wheeling CowboyCop who yells, cusses, gives a fuck when it ain't his turn to give a fuck, and generally plays by his own rules, whereas Bunk is quiet, direct, and by the book.
** Avon Barksdale and Stringer Bell possess this as well. Avon's the shrewd but hotheaded leader of the Barksdale organization, while Stringer generally seeks to avoid conflict and instead see the practical side of things, and attempts several times to make legitimate business pursuits.
** Homeless heroin addict Bubbles is the Blue Oni to his more impulsive friend Johnny Weeks and later to naive protege Sherrod. [[spoiler:Both Red Onis die due to their incautious nature while Bubbles [[EarnYourHappyEnding escapes the street]]]].
** Felicia "Snoop" Pearson and Chris Partlow, the enforcers for up-and-coming drug dealer Marlo Stanfield in Season Three, also form this dynamic. However, the one time Chris truly loses it, even Snoop is amazed.
* Jed Bartlet (red) and Leo [=McGarry=] (blue) from ''Series/TheWestWing'' fit this trope to a tee -- in fact, a good portion of Leo's ''job'' is to act as Bartlet's cool-headed, hard-nosed, deep-thinking Blue Oni counterpart, pulling the passionate, sensitive, deeply moral, and idealistic President back from the brink with logical arguments when he gets too angry, vengeful, excited, righteous, irrational, or quixotic.
* [[TheSpock Spock]] (fittingly costumed in blue) is a classic blue oni on ''Series/StarTrekTheOriginalSeries''; on the occasions when they're not all chumming it up as a PowerTrio, [[TheKirk Kirk]] and [[TheMcCoy McCoy]] each often serve as the red oni to his blue, depending on who's playing off whom at the moment. Red and blue aren't specifically used as contrasting colors for them--[=McCoy=] wears blue as well--but their red human blood and his "cooler"-colored green Vulcan blood are often contrasted.
** According to Shatner's autobiography, one problem they had with the original pilot, The Cage, is that Captain Pike and Mr. Spock were too similar. If you were going to have an unemotional Mr. Spock, then the captain needed to be very emotional so that they could play off of each other, and that's how Shatner played him. Also, the show originally was meant to be Kirk and Spock, and the [=Kirk/Spock/McCoy=] trio developed on its own. (Note that only Shatner and Nimoy have "I get what he gets" clauses in their contracts.)
*** However, in "The Cage", Spock wasn't unemotional at all. It was Pike's first officer, Number One, who was logical and calm, cool, and collected.
** Also, the show buys into this trope in a more general way: science and medical personnel, the knowledge-oriented "brains", wear blue, while operations; security and engineering, the action-oriented "brawn," wear red.
*** Creator/WilliamShatner and Creator/LeonardNimoy themselves are RedOniBlueOni. While William Shatner...won't...hesitate...[[LargeHam tochewupthescenery]]...and...MAKE HIS PERFORMANCE LARGER THAN...[[SayMyName LIIIIIIIIIIIIFE]], Leonard Nimoy focuses on portraying the complexities of a more nuanced character.
** Is that why redshirts always die?
** In ''Series/StarTrekDeepSpaceNine'', we have the rival temporal beings the Prophets (very cold in their interactions, theme color blue, basically "good" if kind of confusing about it) and the Pah-Wraiths ([[EvilIsHammy subtle about nothing]], spewing red flames all over the place, unmistakably evil).
** In a more general sense, the Federation (blue) and the Klingons (red) fit this pretty well in the 24th century, including the color scheme (for instance, the graphics used for their transporters and their emblems).
*** Despite that Worf is a blue Klingon and Jadzia is a Red Starfleet officer.
** Jadzia is the [[ColorCodedCharacters blue oni]] in her friendship with Kira -- Jadzia often being more level-headed and relaxed, while Kira is...[[FieryRedHead Kira]] .
** In any episode featuring the Mirror Universe, the mirror characters are quire ''literally'' the Red oni to the main series' Blue. However, only in ''Series/StarTrekDeepSpaceNine'' do characters actually meet their mirrors in person.
* ''Series/ICarly'' has red Sam and blue Carly, red Sam vs. blue Freddie, Spencer vs. the community art teacher....
* [[ActionMom Sarah]] and [[EmotionlessGirl Cameron]] from ''Series/TerminatorTheSarahConnorChronicles''.

* While not on the same shows (or even the same channel), "{{dueling|Shows}}" chefs Buddy (''Series/CakeBoss'') and Duff (''{{Series/Ace of Cakes}}'') have opposite personalities: Buddy is extremely HotBlooded while Duff is considerably more relaxed; this extends to their surroundings: Buddy's bakery is a neighborhood institution and is mostly staffed with his family (including his [[CoolBigSis four older sisters]]) while Duff only does specialty cakes and is surrounded by his friends.
** The promos for both of these shows does the same. The promos for ''Series/CakeBoss'' are usually with a warm reddish background, with the famous red TLC logo. In contrast, most of the promos for ''Series/AceOfCakes'' are done in shades of blue and even color the Food Network logo blue.
* ''Series/BlakesSeven'' has two pairs of these, one on each side, for the first two seasons: red oni Roj Blake, passionate freedom fighter, frequently reckless, and his {{Lancer}}, blue oni Kerr Avon, coldblooded "what's in it for me?" tech, versus blue oni Servalan, primary power of the evil Republic, and her revenge-obsessed red oni, General Travis.
** In season 3, with Blake vanished, Avon ends up stuck with red oni/brash youth Tarrant while fugitive Servalan doesn't bother to replace the dead Travis.

* ''Series/VeronicaMars'':
** The Casablancas brothers: Dick is stupid, impulsive, never thinks things through, loud, and sex-obsessed. Beaver is intelligent, quiet, reserved, [[spoiler:manipulative, secretive, and completely ruthless]].
** Logan and Duncan. Duncan (blue) is reserved and somewhat emotionally restricted, whereas Logan (red) is pretty much the dictionary definition of HotBlooded.
** And, in flashbacks, Lilly and Veronica. Lilly was the brash, wild one (red), whereas Veronica was sweet and demure (blue) before ([[BreakTheCutie things changed]]).
* ''Series/ThePersuaders'', an English crime series, has two main characters: the aristocratic Brett Sinclair (Blue), who is cultured, clever, charming, and has a dry British humor, and Danny Wilde, a self-made American rich (red), who is hotheaded, uncultured, and very enthusiastic.
* ''Series/BuffyTheVampireSlayer'' and ''{{Series/Angel}}'':
** Both shows have this with the vampires Spike and Angel. The former being Red, the latter being blue. Especially in Season Five of ''Angel''.
** Also, Buffy and Kendra. Kendra seems to be blue to Buffy's red because she's a more classically trained by-the-book slayer yet her lack of experience and gung-ho attitude puts her on the red.
** Faith and Buffy after Kendra dies. And maybe Willow and Tara in season six.
** When Willow and Tara first meet in Season 4, Tara wears blue and Willow wears red -- Tara is shy, cautious yet with longer experience in magic use, while Willow is more powerful, impulsive and (by that stage) outgoing in personality.
** Halfrek is more easygoing and worldly compared to the workaholic and awkward Anya.
* A nice example in ''Series/HomicideLifeOnTheStreet'' with the duo Bayliss/Pembleton. Bayliss is a somewhat {{Emo}} young man who is tragically unable to keep emotionally distant from his job and is given to outbursts of violence, but is also caring and sensitive. Pembleton is an older, smarter, educated, cold, and occasionally smug professional.
* At the end of the pilot of ''{{Series/Leverage}}'', you see a group shot in which the two most hot-headed and aggressive of the crew (Nate and Eliot) have on red ties, and the two most calm and collected members of the team (Sophie and Hardison) are wearing blue. Of course, Parker, being the [[HeroicComedicSociopath resident sociopath]], has no color scheme.

** As of season 9 onwards this trope is taken UpToEleven, with Sam as the coolheaded Blue Oni who tries to take care of Dean's (extremely) HotBlooded Red Oni. Doesn't exactly helps that Dean was a demon through season 10.
* ''Series/JeevesAndWooster'' -- Jeeves is the level head (Blue) to Bertie's naïve optimism (Red).
* ''Series/SaturdayNightLive'' gave us loud, cocky Wayne Campbell (red) and shy, nerdy Garth Algar (blue).

* On ''Series/TwentyFour'', Jack Bauer and Tony Almeida play these roles to each other -- with Jack as the RabidCop red oni and Tony as the (relatively) controlled, business-like blue oni.

* ''Series/TheMightyBoosh'': Many characters pair off and start redding and bluing it up, especially anyone in a conversation with Naboo, the show's resident Blue Oni. Howard and Vince often play with the red and blue chemistry, but they're more like a couple of purples putting up a front.
* [[HairTriggerTemper Fiona]] and [[TheChessmaster Michael]] have been this since the very start in ''Series/BurnNotice''. Now that [[SixthRanger Jes]][[HotBlooded sie]] has been added to the team, (who is both a male Red Oni and also a spy like Michael) it brings up all sorts of interesting chemistry, not to mention the vastly different approaches that Jessie and Michael bring to their job.
* The main stars of ''Series/MythBusters'', Adam Savage and Jamie Hyneman form up very solidly into these characterizations. Adam is exuberant and emotional, often laughing and exclaiming while on the job. Jamie is stiff, cool and analytical, always in control of himself. Behind the scenes, they admit that their completely incompatible personalities had prevented them from becoming friends in spite of their professional respect for each other.
* ''{{Series/Merlin|2008}}'':
** Merlin and Arthur, with the quieter, more sensitive Merlin usually in darker, earthier colors while Arthur usually wears brighter, flashier clothing. Somewhat {{justified|Trope}} as Arthur is a prince and would wear fancier clothing.
** Merlin (Red Oni) to Kilgharrah (Blue Oni)
** Morgana (Red Oni) to Agravaine (Blue Oni)
** Uther (Red Oni) to Gaius (Blue Oni)

* In the early seasons of ''Series/{{Farscape}}'', D'argo and Zhaan have this relationship, down to the colors. It's played with, though, as both also have HiddenDepths. D'argo, at heart, wanted nothing more than a simple farm life with his family, while Zhaan's cool exterior hides a seething rage that is terrifying to witness when it breaks through.
** Then when [[ManicPixieDreamGirl Chiana]] came along and hooked up with D'Argo, she was definitely the red to D'Argo's blue.
** Aeryn was the blue to Crichton's red.
** [[TheHero John Crichton]] and [[MagnificentBastard Scorpius]] can also fall under this heading, particularly when they're forced to [[EnemyMine team up]]: Crichton is outgoing, exuberant, and (especially in the later seasons) more than just a bit crazy, while Scorpius is cold, calculating, manipulative, and ruthless. Once again, both have hidden depths: for all his eccentricities, Crichton is still a scientist, and by the end of the series, he's developed a knack for planning ahead and [[XanatosSpeedChess adjusting said plans at speed]]; Scorpius, on the other hand, hides a ''vicious'' temper under his reserved exterior.
* ''Series/BlueBloods'': Henry and Danny are red onis; Frank, Erin, and Jamie are blue onis.
* ''Series/BabylonFive'': Bester was definitely cool and calculating blue to Garibaldi's indignant and angry red in their ongoing conflict.
* ''Series/{{Battlestar Galactica|1978}}'':
** Apollo is blue and Starbuck is red. Boomer can be the blue to Starbuck's red as well.
** Same would go for Starbuck's lovers, the hot-tempered Athena (red) and the more tolerating Cassiopeia (blue).
** The spiritual Adama (blue) and the cynical Tigh (red) could arguably fit the bill as well.

* In BBC's ''{{Series/Sherlock}}'', Sherlock Holmes is the intelligent, aloof Blue Oni to John Watson's more emotional Red Oni.
** Though they equally enter TranquilFury mode, and Sherlock's [[RedOniBlueOni Red Oni]] moments are shown when it involves a case or if he's ''really'' furious or whatever. Like, if BigBrotherInstinct is activated. Also, John's [[RedOniBlueOni Blue Oni]] moments are shown when it comes to dangerous situations. Oh, and, Sherlock ''did'' [[TookALevelInKindness become more friendlier]] but is still [[TheStoic stoic.]]
** Also, John's a [[RedOniBlueOni Blue Oni]] to Sherlock's [[RedOniBlueOni Red Oni]] in that he's a ShrinkingViolet, whereas Sherlock, well....is a [[BunnyEarsLawyer Bunny Ears Detective]]. And John's the OnlySaneMan.

* ''Series/{{Charmed|1998}}'':
** The charmed ones (The three Halliwell sisters): In the early seasons there was the oldest sister Prue (Generally blue as she was the most mature and responsible and [[PromotedToParent often acted as a mother figure to her younger sisters Piper and Phoebe]]. However, she was also short-tempered and high strung at times and could easily turn red if provoked, especially when Piper and Phoebe were in danger.), the middle sister Piper (Initially the bluest of the sisters: Meek, timid, TheQuietOne, and often played mediater to Prue and Phoebe. [[TookALevelInBadass However, she became much more red in later seasons as she grew more assertive, bossy, and temperamental.]]), while impulsive, free-spirited youngest sister Phoebe was a definite red. In later seasons after [[spoiler: [[RealLifeWritesThePlot Prue's death]]]], the Halliwell's newly discovered half sister Paige is the blue to Piper and Phoebe's red.
** In the first season, there is Andy Trudeau (red) and Daryl Morris (blue).
* An unusual example in ''Series/AgentsOfSHIELD'' with [[TheDividual FitzSimmons]]. While Simmons is generally the blue to Fitz's red, they each display some specific traits associated with the other. For example, Simmons shows a reddish tendency towards adventurousness and excitability when confronted with the unknown, while Fitz has the contrasting bluish qualities of cautiousness and anxiety under the same circumstances.

* A recurring dynamic on ''Series/SchittsCreek'', one that seems to run in the family:
** Responsible businessman Johnny Rose and dramatic, capricious Moira Rose are still deeply in love after nearly 40 years of marriage. Johnny usually wears suits in some shade of blue or gray, while Moira is known for her flashy wardrobe and wig collection.
** Passionate David Rose is the red to his level-headed boyfriend Patrick's blue. Patrick nearly always wears blue clothes, and the one time normally black and white clad David was seen wearing red/orange clothes was when Patrick serenaded him.
** Former WildChild and Red Oni Alexis Rose originally breaks up with NiceGuy Ted (who, as a vet, is often seen in blue scrubs) in season 2 because she's used to dating bad boys, but later falls for him again when she comes to appreciate how kind and down-to-earth he is.

* ''Series/DeadToMe'' has the hot-headed and short-tempered Jen (Red) and the optimistic, empathetic Judy (Blue).

*** The children and parents - Wataru is the Blue Oni to his father's Otoya Red Oni, Megumi is Red Oni to her mother's Yuri Blue Oni, Taiga is Red Oni to his father's King Blue Oni, while Kivat III is Red Oni to his father's Kivat II Blue Oni.
*** Nago (Blue) and Wataru (Red) - sometimes inverse
*** The IXA users - in 2008 we have Nago (Blue) to Kengo (Red), while in 1986 there are Otoya (Red) and Jirou (Blue)

*** [[spoiler:Just like in the case of Kenzaki & Tachibana and Kagami & Tendou, the colors of the changed forms and dancing groups of these two are reversed - Gaim is navy, while Baron is red]].
** ''Series/KamenRiderDrive''' has two Red Onis - the main character Shinnosuke Tomari (Drive) and overconfident Gou Shijima (Mach), while the Blue Oni is calm grim reaper Chase (Chaser).
** ''Series/KamenRiderGhost'' - Tenkuuji Takeru (Ghost) is red, while Fukami Makoto (Specter) is blue.
*** Mirrored by the colors - Ghost's main form is orange (red if used the Toucon Boost), while Spectre's is blue.
** ''Series/KamenRiderExAid'' - main character Hojo Emu (Ex-Aid) is red, while Hiiro Kagami (Brave) is blue.
*** Mirrored by the colors - Ex-Aid's main form is pink, while Brave's is blue.
** ''Series/KamenRiderBuild'' - loves this trope:
*** The two main characters of the show - a calm but caring genius Sento Kiryu (Build) is the Blue Oni while a loud, not-to-smart hotheaded boxer Ryuga Banjo (Cross-Z) is the Red Oni. However, Build's main form (Rabbit-Tank) is colored both red and blue, while most of Cross-Z's forms are blue.

*** The Washio Brothers - Rai (Red) and Fu (Blue)
*** [[spoiler:The two personalities of Build - Sento Kiryu, a genius who wanted to use Build to stop the war and reunite the country is the Red Oni to Takumi Katsuragi (Sento's real identity), a genius, who is the creator of Build and who wanted to use it merely as a weapon in war to conquer Seito and Hokuto, what makes him the Blue Oni]]
*** [[spoiler:The two personalities of Blood Stalk - the ex-astronaut and Misora's loving father Souichi Isurugi is the Red Oni, while the main villain of the show - a parasite named Evolto, which is hosted by Souichi, wants to destroy the world and is the mastemind behind the whole story and the Skywall tragedy, which makes him the Blue Oni]]
*** [[spoiler:The two transformed forms of Gentoku - a cunning Night Rogue is the Blue Oni to the brute Kamen Rider Rogue]]

** ''Series/MightyMorphinPowerRangers'' fit the trope to an extent - the Red Ranger was the confident, extremely physical leader of the band while the Blue Ranger was the intellectual brainiac of the bunch.
*** Of course ''Series/KyoryuSentaiZyuranger'' is rather different from its American adaptation - Tyrannoranger Geki is calm and smart by default, as Triceraranger Dan is dumb, brash, and wanting to rush into a fight.

* Jack O'Neill and Dr Daniel Jackson from ''Series/StargateSG1'' could fit into this trope as many of the earlier episodes' conflict came from O'Neill's emotional pragmatism conflicting with Daniel's intellectual desire to study and understand various things. Interestingly, this is often reversed in later seasons - Jack descends into rational, Black-Ops mindset as Daniel plays up his I-empathize-with-everyone side.

** [[TheCaptain Mal]] and [[TheMedic Simon]] are set up at the start to look like Red Oni and Blue Oni; Simon's even set up to look like a villainous Blue Oni. Then the truth is revealed and from that point on, it's very clear that while they superficially look like an ideal RedOniBlueOni example, they're actually a case of NotSoDifferent, as Simon is every bit as passionate and willing to break the rules and law as Mal. As it turns out, [[HiddenDepths he's even got a better talent for crime than Mal]] - at least, when it involves a subject he's familiar with.

* This trope fits very well with ''{{Series/Lost}}''. Jack - though a doctor, which is very blue in nature - is a very passionate, people-oriented, and frequently rebellious leader. Locke, on the other hand, is more preoccupied with spiritual matters, such as destiny and purpose, as well as more learned in a greater variety of fields. Interestingly enough, though Locke has also frequently shown signs of the blue oni villain through his coldness towards others, Jack's ruthlessness is far more potent, as depicted when [[spoiler: Locke cannot bring himself to shoot Jack in order to stop him from talking to the freighter people, but Jack is fully willing to shoot Locke when the two next encounter each other.]]

** Jadzia is the [[ColorCodedCharacters blue oni]] in her friendship with Kira - Jadzia often being more level-headed and relaxed, while Kira is...[[FieryRedHead Kira]] .

* ''Series/JeevesAndWooster'' - Jeeves is the level head (Blue) to Bertie's naïve optimism (Red).

* On ''Series/TwentyFour'', Jack Bauer and Tony Almeida play these roles to each other - with Jack as the RabidCop red oni and Tony as the (relatively) controlled, business-like blue oni.

* Agent Mulder from ''Series/TheXFiles'' is a red oni, while Agent Scully is a blue oni.

* ''Series/{{Community}}'': HeterosexualLifePartners Troy and Abed. Troy, a [[LargeHam highly expressive]] LovableJock, is the Red Oni to Abed, a [[TheStoic stoic]], [[AmbiguousDisorder undiagnosable]] nerd.

* {{Series/Community}}: Jeff and Annie are this throughout the series. Annie is red whilst Jeff is blue, and this is even highlighted by the colours they wear in the Season 3 episode Digital Estate Planning.

* ''Series/TheDakotas'': Deputy J.D. Smith, a reformed hired gun and a textbook {{Lancer}}, is the Red Oni to his by-the-book Blue Oni boss, Marshal Frank Ragan. Smith tends to bend the rules and do things Ragan's not exactly willing to do, forcing Ragan to remind him he's a lawman now and can't always solve everything by shooting someone. In later episodes, Smith and Ragan consciously use this dynamic (unbeknownst to the other two deputies as well as the outlaws) to put one over on someone they're trying to bring to justice.
