!!Film - Animated
* Tiana and Charlotte from ''Disney/ThePrincessAndTheFrog''. They also fit the TomboyAndGirlyGirl mold as well, with Charlotte being the [[CuteButCacophonic loud]], over-dramatic, [[TheDitz ditzy]], SpoiledSweet dreamer and Tiana being the quieter, more [[CloserToEarth down-to-earth]] working girl. Also, one scene has Charlotte in a pink ballgown with Tiana in a (borrowed) blue dress.
** Tiana and Prince Naveen also fit the description to a T, with Tiana being a {{Workaholic}} and Naveen being overly laid back and lazy.
* Lightning [=McQueen=] and Doc Hudson from ''WesternAnimation/{{Cars}}''.
* Also by Pixar, Russell and Carl from ''WesternAnimation/{{Up}}''.
* In ''Disney/{{Pocahontas}} '' The British Settlers and The American Indians this was cemented during the song "Savages."
* In ''WesternAnimation/ThePrinceOfEgypt,'' the DistantDuet "[[http://www.youtube.com/watch?v=-tVTEyuCKn4 The Plagues]]" has Moses in orange light and Ramses in blue shadows at the end of the song. Their clothing choices throughout the film follow the same color scheme. It fits their overall personalities as well, with Moses being the impulsive and exuberant one that gets them both into trouble, and Rameses being the overly thoughtful, in-control type hailed as a great leader. (Though ultimately, Moses’s passionate nature results in empathy and compassion and enables him to save his people; whereas Rameses’s analytical, rule-following stoicism makes him cold and ruthless and causes his greatest fear—ruining his father’s legacy—to come to pass.)
* Anna and Elsa from ''Disney/{{Frozen}}''.

* AbbottAndCostello.
* Peter Jackson's Middle-earth universe:
** In the film characterization of ''Film/LordOfTheRings'':
*** There's the angry dwarf Gimli and the elegant Legolas.
*** Then there's the proud [[BoisterousBruiser Boromir]] and the world-wise Aragorn, though the [[WarriorPoet more thoughtful]] Faramir (blue) can be paired with his brother as well.
*** In case of the four Hobbits, Sam and Frodo as well as Pippin and Merry. Or [[LetsGetDangerous Merry and Pippin are the red]] to [[ThouShaltNotKill Frodo and Sam's blue]].
** Then comes the film characterization of ''Film/TheHobbit'':
*** Bilbo (red) and Thorin (blue), since Bilbo is excitable and somewhat silly whereas Thorin remains dignified. It especially helps that the two wear their distinctive colors.
*** Also, [[BoisterousBruiser Dwalin (red)]] and [[TeamMom Balin (blue)]].
*** [[FoolishSiblingResponsibleSibling Kíli (red) and Fíli (blue)]] can fit this trope as well.
*** There's also Tauriel and Legolas in the last two films. Tauriel can also be paired with Thranduil, who is also blue.
* ''Film/{{RedTails}}'': The primary character conflict is between {{Hero}}/{{Lancer}} duo Easy and Lightning. Blue and Red respectively.
* In the ''Film/{{Hellboy}}'' series, the title character (sloppy, hot-tempered demon dating a human flamethrower) and Abe Sapien (studious, slightly prissy gillman) are actually addressed as "Red" and "Blue" respectively; although this is due to, y'know, their actual skin color, the association still fits. Hellboy and Krauss, too, particularly when Krauss is possessing that Golden Army trooper in the final scene - all his glowy bits go blue. They fit the personality portions of this trope to a T.
* ''StarWars''
** The Sith and the Jedi fits this trope to a T. The Sith wield red lightsabers and are defined by their passions and their ambitions. While the Jedi typically wield blue or green lightsabers and are presented as more intellectual and steeped in tradition.
** On a more individual level, the master/apprentice relationship between Obi-Wan Kenobi and Anakin Skywalker during the prequel trilogy. Obi-Wan is the more cautious and thoughtful blue Jedi and Anakin, being younger and more ambitious, represents the passionate red. Of course, this speaks volumes about the paths the men choose by the end of the end of said trilogy.
** Later (or earlier, depending on how you look at it), the trope is played with by Han and Luke. They switch roles as CharacterDevelopment ensues: Luke starts out as the impulsive idealist to Han's world-weary cynic, while by the third film Luke is the disciplined and determined warrior and Han is the emotionally driven one.
* In the movie version of ''LAConfidential'', Edmund Exley is a near-perfect example of a blue oni (and nearly always dresses in a blue suit to boot), while Bud White is very much a red oni (complete with brown/maroon suit).
* In ''Film/MenInBlack'', Agent K is the serious, deadpan blue oni mentor while Agent J is the wisecracking, impulsive red oni rookie.
* JamesEllroy seems to love this trope; the two detectives at the center of his ''The Black Dahlia'' are even referred to explicitly as Mr Fire (red) and Mr Ice (Blue).
* The Will Ferrell movie ''{{Blades of Glory}}'' has Chazz Michael Michaels, the improvisational, womanizing idiot Red Oni, and Jimmy Macelroy, the technical, thoughtful man-child Blue Oni. This is even reflected in their "Fire and Ice" costume.
* From ''Film/{{Watchmen}}'', Rorschach/The Comedian/Ozymandias to Dr. Manhattan. Actually, ''everybody'' is a Red Oni compared to Dr. Manhattan.
** A better example might be that Rorschach is Red Oni and Nite Owl II is Blue Oni.
* Every ''Film/DieHard'' movie has one or more elements of this. John [=McClane=], the hot headed runner and gunner always goes up against a calculating intellectual BigBad. The first two movies also have a subplot involving [=McClane's=] "Red Oni" tactics budging up against the "Blue Oni" by-the-book style of the authority.
* The Henke and Genji clans in ''SukiyakiWesternDjango''.
* ''Film/XMen'':
** The movies had the rivalry between Pyro and Iceman.
** Victor is the red to Logan's blue in ''Film/XMenOriginsWolverine''.
** Erik and Charles in ''Film/XMenFirstClass''.
* ''Film/{{Underworld}}'' 'verse has raging werewolves versus cold, calculating vampires.
* ''HardCoreLogo'' has the intense, impulsive Joe Dick and the quieter, more calculating, ambitious Billy Tallent.
* In ''Film/{{Serenity}}'', Mal is a red oni of the heroic type and the Operative is a blue oni of the villainous type. Mal wears warm tones while the Operative dresses in blue.
* Ferris Bueller and Cameron Frye in ''Film/FerrisBuellersDayOff''.
* Del Griffith and Neil Page in ''PlanesTrainsAndAutomobiles''.
* ''Film/FightClub'': Tyler is impulsive and rash, whereas the Narrator is a calm and cool businessman. Their different personalities are, of course, all mixed-up in the heat of the fight.
* ''Film/TradingPlaces'' has Billy Ray Valentine and Louis Winthorpe III.
* The ''Film/BackToTheFuture'' movies have Marty [=McFly=] and Dr. Emmett "Doc" Brown.
* ''Film/TopGun'' has the brash/hot-headed Maverick play Red Oni to the Blue Oni of his level-headed copilot Goose and their more by-the-book fellow pilot Iceman.
* Lloyd Christmas and Harry Dunne in ''Film/DumbAndDumber'', as illustrated by their {{Tacky Tuxedo}}s.
* Franchise/IndianaJones is the red oni to his father Henry Sr.'s blue oni in ''Film/IndianaJonesAndTheLastCrusade''.
** In ''Film/IndianaJonesAndTheKingdomOfTheCrystalSkull'', Jones is the blue oni to Mutt's red oni, with good reason: [[spoiler:Mutt is really his son.]]
** In ''Film/RaidersOfTheLostArk'', Belloq is the blue oni to Indy's red oni. This ties into their preferred methods for acquiring artifacts. Indy is hands-on and collects them personally. Belloq hires other people to do the dirty work while he stands off to the side acting sophisticated.
* OsmosisJones has this with a color inversion. Ozzy is the Red Oni and Drix is the Blue Oni. This is despite Ozzy being blue and Drix being red.
* It could be said that Buffalo Bill is the red oni to VillainProtagonist [[SilenceOfTheLambs Hannibal Lecter's]] blue oni.
* In ''Film/SenseAndSensibility'' references it in the title and has a few examples.
** Straight-laced and collected Elinor is blue, while the flighty and passionate Marianne is red.
** The men who court Marianne: Willoughby is fun and dashing, but false. Colonel Brandon is reserved but true.
** Charlotte Palmer is bubbly and easily excitable, while her husband Mr. Palmer is quiet and sour.
* Thor and Loki from ''Film/{{Thor}}'' and ''Film/TheAvengers'' are the epitome of this trope. Although, given their colour schemes, it's more like Red Oni, Green Oni.
** Another ''Avengers'' example would be Iron Man & Captain America. The brash and arrogant antics of the red-clad Iron Man really don't sit too well with the humble-natured and calm Captain America, who wears blue.
** In the regular ''Film/IronMan'' films, James Rhodes is the blue Oni to Tony's red. And, like Rogers, he is usually seen wearing blue.
** Another member of the Avengers who embodies both Onis is mild-mannered scientist Bruce Banner and his alter-ego the Hulk, who is literally a raging id.
* In ''Film/WilliamShakespearesRomeoAndJuliet'', the Montegue men are Anglo guys in Hawaiian shirts who seem to be a bit more loose and rough. The Capulets are angrier, sharply-dressed Latinos.
* In the 2011 film ''Film/{{Warrior}}'': Tommy is red, Brendan is blue. Their gloves are color-coded for your convenience. %% This entry was added automatically by FELH2. In case the wording doesn't make sense, rewrite it as you like, remove this comment and tell this troper.
* ''Film/PulpFiction'' [[ZigZaggingTrope zig zags this trope]] with Jules and Vincent. On the surface, the former is hotheaded and the latter is calmer, if not outright aloof. As the film progresses, it's quite clear that Jules is the one with the more level head and that his "Bad Motherfucker" tendencies appear only when someone (usually Vincent) says or does something really stupid. Vincent, on the other hand, is a bumbler, needlessly starting a brief argument with the Wolf when presented with advice to solve [[IJustShotMarvinInTheFace a problem he started]] and leaving dangerous stuff around for people to find [[spoiler: (Mia with the drugs, Butch with the sub-machine gun) ]].
* ''Film/LethalWeapon'' has Riggs as the Red and Murtuagh as the Blue.
* The two burglars in [[HomeAlone Home Alone]]: Harry is the blue oni and Marv the red oni.
* In ''Film/PacificRim'', Newt and Gottlieb are red and blue respectively.
* In ''[[Film/{{Rush2013}} Rush]]'', the hardcharging partyboy James Hunt is the red oni to his rival Niki Lauda's cool, cerebral blue oni.
* In ''Film/VivaMaria'', trigger-happy Bardot!Maria and cerebral Moreau!Maria.
* In ''Film/TheLegendOfFrenchieKing'', aggressive and impatient Marie versus calculating and distant Louise.
* In ''Film/BlondeInBlackLeather'', Claudia starts out as idealistic and naive, with Monica passing for cool and street-smart (they're also dressed in the respective colors). They switch roles as the movie goes on, with Claudia becoming savvier and more down-to-earth while Monica comes off as something of a manic-depressive.
* ''Maiko Haaaan!!!'' combines this with the traditional kabuki hero/villain colour schemes. The protagonist, Onizuka Kimihiko, is very excitable and is driven by his passions while the antagonist, Kiichiro Naito, is much more reserved and collected. [[TheAlcoholic Unless he's drunk]].
