* ''Series/SchittsCreek'': A recurring dynamic on the show, one that seems to run in the family:

* ''Series/SchittsCreek'': 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 seranaded him.

* ''Series/SchittsCreek'': 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 seranaded him.

** ''Series/KamenRiderRyuki'' has two main heroes: Kido Shinji (Ryuki), who is [[DumbIsGood impulsive and idealistic]], and Akiyama Ren (Knight), who is [[TheStoic stoic]], cool, and sometimes dangerously close to JumpingOffTheSlipperySlope. Ryuki's armour is red; Knight's armour is normally black, but later in the series, he acquires a powerup that turns him blue so that [[ColorCodedCharacters the colours fit the trope]].

** ''Series/KamenRiderBlade'' has Blade as the Red Oni (and TheHero) and Garren as the Blue Oni (and TheLancer). Played with in that their main colors are the opposite of their personality (Blade, the Red Oni, is mostly blue in color, while Garren, the Blue Oni, is mostly red.)

*** Kougami Foundation: Kougami and Dr. Maki.
*** Greeed: Uva and Kazari.

*** [[spoiler:Just like in the case of Kagami and Tendou, the colors of the changed forms and dancing groups of these two are reversed]].

** ''Series/KamenRiderBuild'' - 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 other sets from this show are:
*** Touto's Prime Minister Taizan Himuro (Blue) and his son Gentoku (Red)
*** Gentoku (Red) and Nariaku Utsumi (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/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/Merlin}}'':

* ''Series/{{Charmed}}'':

*** Prime Minister Taizan Himuro (Blue) and his son Gentoku (Red)

*** Taizan Himuro (Blue) and the other two prime ministers (Red)

** '*Series/KamenRiderExAid'' - main character Hojo Emu (Ex-Aid) is red, while Hiiro Kagami (Brave) is blue.

* ''Series/Arrowverse'':

* The two main heroes of the Series/ArrowVerse fit this. Oliver Queen/Green Arrow is TheStoic, analytical, and reliant on his [[TheStraightAndArrowPath precision in archery]]. Barry Allen/The Flash is more emotional, idealistic, and blitzes through his enemies and life with his SuperSpeed.
** Series/{{Supergirl}} is the emotional Red Oni while her adopted sister, Alex, is the calm Blue Oni.

** Arya is the gutsy, extroverted red to Gendry's calmer, introverted 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.

** TheStoic, grim, peace-loving Blue Ned Stark and the boisterous, hedonistic Red Robert Baratheon.

** Joffrey serves as the violent, impulsive Red Oni to the calm and intellectual Tyrion, the cold and calculating Tywin, and the meek, soft-spoken Tommen.

*** Of course ''Series/KyoryuSentaiZyuranger'' is rather different from its American remake - Tyrannoranger Geki is calm and smart by default, as Triceraranger Dan is dumb, brash, and wanting to rush into a fight.

* 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.

* ''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.

** The promos for both of these shows does the same. The promos for ''CakeBoss'' are usually with a warm reddish background, with the famous red TLC logo. In contrast, most of the promos for ''{{Series/Ace of Cakes}}'' are done in shades of blue and even color the Food Network logo blue.

* While not on the same shows (or even the same channel), "{{dueling|Shows}}" chefs Buddy (''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.

** Those actors play the same roles as Heatwave and Captain Cold (respectively) in ''Series/TheFlash'' and ''Series/LegendsOfTomorrow''.

* This dynamic plays out with several characters in ''TheWire'':

* Jed Bartlet (red) and Leo [=McGarry=] (blue) from ''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.

* Although Justin and Alex, from ''{{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 two main heroes of the Franchise/ArrowVerse fit this. Oliver Queen/Green Arrow is TheStoic, analytical, and reliant on his [[TheStraightAndArrowPath precision in archery]]. Barry Allen/The Flash is more emotional, idealistic, and blitzes through his enemies and life with his SuperSpeed.
