Eye Colour Change

Go To
From Jedi Knight (benevolent eyes) to Sith Lord (malevolent eyes).

An Eye Colour Change is when a character's eyes change colour in response to some stimuli. The colour the eyes change into depends on the event and the character, but it can be anything from a shift in hue to something as dramatic as brown eyes turning bright yellow and round pupils lengthening into slits.

This is generally a sign that something major has just happened. A possession, a shift in alignment, the acquisition of supernatural power (see also Magical Eye, if the power is directly tied to the eye), trauma, anything significant can trigger an Eye Colour Change. Being a robot (or a cyborg with Electronic Eyes) is also a common explanation.

Does not apply to a Adaptation Dye-Job; the eye color variant would be Sudden Eye Color. See also Convenient Color Change, Game Face, Eye Lights Out and Demonic Possession. A frequent feature of Mind-Control Eyes. Red Eyes, Take Warning sometimes happens here.


Not to be confused with Inconsistent Coloring, which is where a character's eyes may change colour due to a mistake, retcon on the artist's part, or due to shifting lighting conditions.

    Anime & Manga 
  • Claymore: The eyes of a Claymore are silver until they use their Yoma powers; this turns their eyes gold.
  • The title character of Rurouni Kenshin changes eye colour to correspond to which Split Personality is in command in the anime.
  • Subaru Nakajima's eyes in Magical Girl Lyrical Nanoha StrikerS are normally green, but turn gold when she enters full Combat Cyborg mode. The first time this is triggered on screen, it also coincides with Unstoppable Rage.
  • In the Bleach anime, Ichigo's eyes change color while in his Hollow form. Not only are they now yellow, the white changes to black. He also tends to get glowing blue eyes sometimes, like he did right before beating Renji.
  • Dragon Ball Z:
    • A Saiyan's eyes turn greenish-blue when he turns Super Saiyan (although it's easily missable, since the other effect of the transformation is much more visible).
    • Their irises also turn red when they start absorbing Bruitznote  Waves when they look at a full moon, as a prelude to the transformation to a Great Ape.
    • A Super Saiyan who has ascended to Super Saiyan Godhood gains red eyes to go with red hair. When the Super Saiyan God goes Super Saiyan, the eyes go back to turquoise, with the hair also matching.
    • Android 21 of Dragon Ball FighterZ has this whenever her evil side takes full control, having red-ring irises on a black sclera just like Super Buu. Significantly, Good 21 retains her normal blue eyes when in her Buu form, showing that she's in control as well as allowing the audience to tell the two apart.
  • Naruto:
    • The Sharingan is a hereditary superpower of the Uchiha clan that allows for Awesomeness by Analysis and causes distinctive change in the eye when used; a more advanced version exists has a different look. Both are unlocked by traumatic experiences.
    • A lot of characters change eye color to correspond with things such as Demonic Possession, unlocking their powers/going into Super Mode, or just giving off a killer vibe.
  • In Tengen Toppa Gurren Lagann, humans who channel enormous Spiral Power have spirals appear in their eyes. This is seen mostly in Lordgenome, but also briefly in Kittan right before his death. Simon's eye also changes during the Giga Drill Break war with the Anti-Spiral after Lordgenome's sacrifice, as well as during the Distant Finale.
  • In Reborn! (2004), Tsuna's eyes are normally brown. However, when he goes into Dying Will Mode, they change into an orange-ish yellow.
  • The eyes of NEXT in Tiger & Bunny typically change to a bright, glowing blue when they activate their abilities. This isn't the case for all of them, however — NEXT with passive abilities don't have an eye color change, the eyes of the two NEXT in Ouroboros glow orange-yellow, and Kotetsu's eyes have recently started turning red to go along with his Power Incontinence.
  • In Yumeria, Neneko has violet/purple eyes, but when mental time traveler Neito takes control of their shared body, they turn green.
  • Inuyasha: Both the title character and his half-brother, Sesshoumaru, have eyes that go completely bloodshot-red when their demonic powers are fully released. However, Inuyasha's eyes also change colour according to whether he is in human (black), normal (gold), or youkai (red) form, because he's a Half-Human Hybrid whose human side is fully expressed during a new moon and whose demon side is fully expressed when he pushes his own natural powers to their limits (in which case, good luck getting him to restrain himself to attacking only the bad guys.)
  • In Digimon Tamers, when Beelzemon makes his Heel–Face Turn, his eyes go from evil red to the green of his previous form, Impmon. (Interestingly, a Beelzemon in a later series is also the new form of a Heel–Face Turn character, but his eyes stay red. It may be because, unlike Impmon, this one's previous form naturally had red eyes.)
  • When Lina Inverse of Slayers fame is possessed by the Lord of Nightmares in the end of Slayers NEXT, her eyes, normally red, appear golden.
  • In Tsubasa -RESERVoir CHRoNiCLE-, vampire's eyes turn gold when they sense blood or are using their powers. Fai experiences this when he is turned into a vampire to save his life.
  • Kagerou Project: Every character's eyes (which are normally either brown, yellow or pink) turn red when they're using their Eye Powers. In some cases, their pupil also becomes a slit (even if they're usually drawn without one). A more serious example comes when the usually pink-eyed Konoha's eyes become yellow with slit pupils. It (along with the rest of his costume turning black) signals that he has been taken over by the Wide-Eyes Snake and become Kuroha.
  • When Hakkai from Saiyuki removes his Power Limiters, his eyes change to golden catlike ones... or rather, only the left one does; the right one is artificial, made to match the other one while in human form, and therefore remains green with a round pupil. The result is somewhat unsettling, preserving a trace of Hakkai's original human self even when he taps into his demon powers.
  • Death Note:
    • Misa Amane's eyes have a habit of this. Multiple times in the anime, her eyes change from brown to blue. It's because she wears blue contacts. There are also times where her eyes are red when she's using her Shinigami eyes to read people's names, but Word of God is that this is stylized.
    • The same thing happens for the other Death Note users with their eye color changing from their original color to red, primarily with the Villain Protagonist Light. His eyes are originally brown, but once he obtains his notebook, his eyes glow red whenever he goes into "Kira mode". The finale even shows his eyes are bright red instead of brown. Word of God is that this is Stylized for the Viewer and his eyes are always brown.
  • In Tokyo Ghoul, this is one aspect of a Ghoul's Game Face. Their eyes transform from completely normal to black schlera and red irises, an indicator of their true nature known as "kakugan" (which just means "red eye").
  • In Sword Art Online, Kirito's pupils change color to gold (or maybe yellow?) when he gets really serious and pulls out all the stops.
  • On Black Butler, Sebastian's eyes are normally a caramel hue, unusual but close enough to brown to normally pass unremarked upon. But when he really means business, his eyes shift to a bright magenta with white flares and he gains Hellish Pupils.

    Comic Books 
  • When Tigress hijacks Flare's body in hope of learning about Teresa's mother, Teresa's eyes change from blue to green.
  • In Afterlife Inc Jack Fortune's eyes were blue before he died, and golden afterwards. Quite what this means is a mystery.
  • The '90s Supergirl comic had Linda Danvers suspecting something was off when she saw that her eyes permanently changed from brown to blue, after being rescued from a certain death by a cult. It's because she WAS dying, and the Matrix version of Supergirl merged with her, causing some of her features to wind up reflected in Linda.
  • Similarly, the Justice Society of America relaunch had a plot point where it was revealed that after Kendra Saunders (the current Hawkgirl) had attempted suicide and been revived, her eyes mysteriously changed from green to brown. This is chalked up to Kendra's soul actually departing and her aunt Shiera taking residence in her body, thus changing Kendra's eye color to what hers (Shiera's) had been.
  • Norman Osborn's eyes change from brown to green when he's using the Green Goblin powers. In The Pulse, this is what first makes Daily Bugle reporter Terri Kidder realize something is very wrong.
  • In The Incredible Hulk, Bruce Banner's brown eyes turning an unnatural shade of green is a common prelude to him Hulking Out.
  • In the final arc of Sonic the Comic, Sonic's eyes turn permanently green after he's attacked by Chaos.
  • Sonic the Hedgehog (Archie Comics) explained Sonic's redesign as being due to external forces. His eyes changed colours from black to green.
  • In a Canardo comic, Alexandra's orange eyes change to white when she's heartbroken from seeing her father, who she wanted to believe was a good person, execute a village of starving circus people.

    Fan Works 
  • Child of the Storm: This happens a lot.
    • The colour Harry's eyes are glowing is basically an indication of his mental state:
      • Solid gold is fine, though you should possibly be wary - he's accessing his psychic abilities, seriously if they do more than just flash gold briefly.
      • If they go red, he's either been possessed by Chthon or enslaved by the Red Room. Either way, you should run.
      • If they go solid white, like, heart of a star white, he's been possessed by the Phoenix or has gone Dark Phoenix of his own volition, and you should find another galaxy to run to.
    • Jean Grey's eyes go amber-red under similar circumstances or when Harry is accessing the Phoenix.
    • And Maddie's eyes go bluish-white under the same circumstances.
    • Carol's go solid green when she's wielding Alan Scott's Green Lantern ring.
    • Thor's eyes go electric blue when he's really pissed off.
    • Like Harry, Gravemoss' eyes go red when he's possessed by Chthon.
  • The Infinity League: Miranda's eyes would change colour when she activates her power. And now, so do the other characters' eyes when they use theirs.
  • Justice Society of Japan: Happens to Kallen early
  • Another Life: Describing the difference between an Author Avatar and her creator, the story states that the former's eyes change color depending on her mood, while the latter's are always the same dull shade.
    "Sarillenne's eyes are bright golden yellow, but they will sometimes turn green when she is happy, or ruby-red when she is angry. Sara's eyes are dull, greyish brown, no matter how angry she gets at the wall-to-wall rejections that make up her life."
  • Venturian Tale: Johnny Ghost's eyes are often portrayed as turning bright red when he turns into Jimmy Casket.
  • How To Drill Your Way Through Your Problems: Taylor's eyes change from brown to blue after she triggers.
  • The Heart Trilogy: Kathryn, the main heroine, was born with her father's golden brown eyes. However, when she had her first vision at the age of six as a Seer, her eyes turned permanently purple. When she dies at the end of Heart of Fire, her eyes gain the color of molten gold. When she's resurrected in the beginning of Heart of Ashes, her eyes remain golden because her connection to Raw Magic is damaged. Once Smaug fixes this, she regains her purple eyes.
  • The Touch of Green Fire: It's shown that Shego wasn't born with green eyes. When she received her powers (which changed her skin to green), her eyes changed from their natural blue to green. Her eyes changing back to blue are a symptom of her power-draining illness.
  • Fantasy of Utter Ridiculousness: Alice Margatroid's eyes shift from a calm blue to a bright yellow when she's struggling to keep her more severe emotions in line, which is usually whenever Marisa or Coop are present.
  • Trade Winds: Using Eagle Vision causes the user's irises to gain a glowing golden ring around the outside, which is how the Chinese delegation realized, in the dark, that Desmond Miles has the prized, allegedly-for-royalty-only "Dragon's Eye", as they call it. Nobody else who isn't in the know seems to notice this — but it's possible only those with the Eagle Vision ability can see it —and when dragons use their Eagle Vision, this doesn't happen to their eyes.
  • Sonic the Continuation: Amy's eyes changed from brown to green after coming into contact with Chaos energy.
  • The Portal: Thomas Smith, who normally has brown eyes, gains blue eyes when he becomes a dragon.

    Sapphire: "They change color every day."

    Film — Animation 
  • In the BIONICLE films, Vakama's Face–Heel Turn and subsequent Heel–Face Turn are represented by his orange eyes turning sickly green, and back. Roodaka, who leads Vakama astray in the first place, has blue eyes that go red when she's angered.
  • My Little Pony: Equestria Girls – Rainbow Rocks: Adagio's eyes briefly flash green at one point when the Dazzlings are at the height of using their song to pit the students against each other. The eyes of their victims likewise flash green on occasion.
  • In Operation: Z.E.R.O., the Delightful Children from Down the Lane lose their blue Mind-Control Eyes when they are temporarily un-Delightfulized and revert to their old selves, the lost and legendary Sector Z. Numbuhs 0.4 and 0.3 have dark brown eyes, 0.2 has green ones, and 0.1's are dark blue. Numbuh 0.5 wears sunglasses that obscure her eyes, but it can be assumed that they too turned back to normal.
  • Sandy from Rise of the Guardians. When he is impaled by Pitch's black sand arrow, Sandy's pupils become darker and more prominent in response to the darkness consuming his body.

    Film — Live-Action 
  • In The Avengers, Loki's staff changes people's eyes blue when he mind-controls them. On the DVD commentary, director Joss Whedon explains that this was actually something they added in post-production to make the difference between brainwashed characters and people acting under their own will clear, and so that there was a clear visual sign in Hawkeye when he finally broke out of it, which makes his teammates taking him back more understandable.
  • In The Lost Boys, vampires' eyes go from their natural colour to red when they transform into 'vampire mode'.
  • The Girl from The Ninth Gate (who is possibly the devil in human form) does this at several points, mostly when her Blood Lust gets going.
  • Star Wars has the phenomenon of "Sith eyes", related to the Dark Side of the Force. They usually aren't permanent and usually manifest when the dark Force-user is enraged (Count Dooku, always calm and collected, never manifests them). Only Darth Maul, who is more or less always belligerent, sports permanent Sith eyes.
  • Judge Doom from Who Framed Roger Rabbit has brown eyes up until he gets squashed by a steamroller, revealing him to be a toon, at which point his natural red eyes appear. This is also the point he stops being calm and collected and starts acting outright psychotic.
  • In the spoof film, Epic Movie, Mystique has mostly a normal blue eye color throughout her brief appearances, like her actress Carmen Electra. However, during the sex scene she has with the main character Peter, she says how she's a shape changer and can change her form into anything. She demonstrates this by changing her eyes to Yellow, with black pupils and dots surrounding it. However, it disappears for the next few shots, until they briefly revert back to Yellow when she says "Come Again?" They disappear again, and return as she starts to expand her body in a fat and flabby grandma with a monobrow at Peter's request. The inconsistent eye colors in this one scene is understandable as this film relies on Negative Continuity. It does the make the scene a lot more disturbing though...

  • Aurora Cycle:
    • Auri's right eye turns permanently white when she uses her Eshvaren powers for the first time while conscious.
    • When Cat is infected by the Ra'haam pollen on Octavia III, the first visible sign is her eyes turning from brown to blue.
  • Black Jewels: Jaenelle Angelline's eyes turn from "summer-sky" blue to "sapphire" when she's in Witch mode.
  • The Brightest Shadow: Characters who become the Hero tend to have their eyes get lighter, eventually becoming unnatural white. It's ambiguous if their natural eye color becomes lighter, but it definitely appears white when the Hero is on a rampage.
  • The Chronicles of Ancient Darkness: After spirit-walking in trees in Oath Breaker, Torak gains tiny green flecks in his eyes. He loses them after the Thunderstar destroys much of the Forest, and regains them following the Rite that brings the First Tree back.
  • In the Codex Alera, the Marat people take on the eyes characteristic of the animal they take as a Bond Creature. In particular, in the first book Kitai's eyes turn green when she bonds Tavi.
  • The Cosmere:
    • The Stormlight Archive
      • It is said that if a person with dark eyes wins a Shardblade their eyes will become light. In the first book, we only see one darkeyes with a Blade (Szeth), and they only turn pale blue when he is actively using the Blade. He notes that this is unique to his Blade, so the full situation remains unclear. It turns out that this is because Szeth is wielding an Honorblade, not a Shardblade.
      • In the second book, we get more detail. Yes, darkeyes permanently turn light once you've bonded with a Blade (which takes about a week). Full Radiants also have their eyes turn light; in fact, this process is what the Shardblades are mimicking. It seems to be the source of the Fantastic Caste System that ranks lighteyes above darkeyes.
      • The influence of Odium has also been shown to give spren and people red eyes, to the point that red eyes are seen as a mark of Voidbringers.
      • Interestingly, Radiants not only get lighter eyes, but may have a completely different eye color, as when Kaladin goes from dark brown to light blue eyes. Dead Shardblades, on the other hand, give a darkeyes a lighter version of whatever his original eye color was (Dark brown to gold/tan, for example).
    • In Shadows for Silence in the Forests of Hell, the ghostly Shades' eyes are a sign of the level of danger they pose. When calm, their eyes are the same misty white as the rest of them. If they glow green, it's a sign that they are alert and looking into the physical world. If they turn red, they're enraged and about to start using their Touch of Death on anyone nearby.
  • In Roger Zelazny's Dilvish, the Damned, some witches have eyes that wax and wane with the moon.
  • Rachel from Cliff McNish's The Doomspell Trilogy has eyes that change colour depending on the spell she is using; these eyes are said to be a wizard trait.
  • In The Door Within Trilogy, the Glimpses eyes change colour depending on their affiliation: Blue for King Eliam, Red for Paragor, and Green for neutral/undecided.
  • Eyes are often very important in Chris D'Lacey's The Last Dragon Chronicles. If it mentions someone's eye color more than once, it's a good bet that it has either changed or will change soon. Brown, blue, green, black, and violet are the most common.
  • In Dune, people exposed to the Spice Melange develop brilliant blue eyes. This includes the whites of their eyes turning blue, not just the iris. This is significant for a number of reasons: Mentats consume spice in order to increase the processing capacity of their brains, and their blue eyes are a sign of their super-human abilities. The Fremen inhabitants of Arrakis also develop the eyes due to their constant proximity to the spice. So when Paul Atreides' eyes turn blue, it symbolizes his transition into a Fremen warrior.
  • A very unsettling example occurs with Ianthe in Gideon the Ninth, after she consumes Naberius's soul. Her eyes keep flickering between her natural eye colour and his, sometimes just becoming entirely pupil-less and white. It's implied that all Lyctors take the eye colour of the cavalier they consumed, as Cytherea's blue eyes are noted as being "someone else's fire," and Harrow refuses to look at her reflection in the epilogue after she's consumed Gideon's soul.
  • Mages in the Heralds of Valdemar series who work with node magic will see their eyes gradually lighten to blue, and their hair turn white — powerful magic has a bleaching effect on its users.
  • In Hercule Poirot, when Poirot is very excited, his green eyes flicker and become steadily greener and greener.
  • InCryptid: All Johrlac have pure white eyes when actively using their telepathy (Sarah calls it a form of bioluminescence). They can still see fine, though focusing on both another mind and their surroundings at the same time can be difficult. The rest of the time, they have Occult Blue Eyes.
  • In the Inheritance Cycle, Solembum has these (and potentially the elves, if you count that they can use their magic to change their forms when they feel like it). In the first novel, he is stated to have red eyes. In the second, he has golden eyes. In the third, he has green eyes. In the fourth, he has blue eyes. This is even lampshaded by Eragon, who quips, "Weren't your eyes red?" which prompts Solembum to change his eyes back to red.
  • In Journey to Chaos, changing eye color or shape is characteristic of mana-born demons, signifying a shift from their sapient form to their monstrous one. Eric Watley has eyes whose pupils turn into slits, the eyes of Nolien Heleti turn entirely red and those of Kallen Selios turn from circles into triangles.
  • In Lightning Dust, the eponymous hero's eyes turn bright yellow from their normal blue when Klaus turns into him, while Daniel's sclera (the white part of the eyes) and pupils turn light and dark blue respectively when he becomes Crystal Eye.
  • In Magic to the Bone, Zayvion has Brown Eyes with flecks of gold... until he leaves the magic grid, whereupon they turn brown. When he drives back, his eyes turn pure gold with flecks of brown.
  • People Molly Moon hypnotizes will have their eyes turn a sickly green to match her own.
  • Rivers of London:
    • This might have happened to Nightingale as part of his Merlin Sickness: he's described as having grey eyes, but an old portrait of him Peter finds (which he assumes to be of Nightingale's father at the time) has blue eyes.
    • In Foxglove Summer, Zoe Thomas had her eyes permanently change from blue to hazel during her childhood run-in with the fairies that led to her baby half-sister being swapped out for a changeling (who was also her half-sister).
  • Oliver Twisted: Oliver's eyes turn silver when harnessing the warlock magic inside him which he calls "the Rage".
  • Septimus Heap: At the end of Magyk, Sarah Heap notices that Septimus' eyes are becoming green from exposure to Magyk when she identifies him as her child.
  • In The Seventh Tower, Icecarl women who become Crones have their eyes change colour three times as their magic grows: to vivid blue as apprentices, to luminous silver as full Crones, and to milky white as Mother Crones.
  • Sister Fidelma has blue eyes that sometimes flash green with her changeable moods. Atypical because hers is a historical fiction series with no hint of magic.
  • Tailchaser's Song: Eyeshimmer's eyes turn from his normal milky blue to a deep blackish-blue when he uses his far-senser powers.
  • The Wheel of Time:
    • Users of the True Power develop black flecks swimming across their eyes as a result of overuse. With continued use, the flecks become more common, and eventually transform the eyes and mouth into caverns of flame.
    • People who awaken as a wolfbrother have their eyes turn gold to match those of a wolf.
  • The Witchlands: The Sightwitches have their eyes turn silver when they are granted the gift of Sight by their goddess. The only two Sightwitches not to have the power, Ryber Fortiza and Eridysi Gochienka, also eventually gained silver eyes.

    Live-Action TV 
  • The 4400: In "Being Tom Baldwin", Isabelle makes her eyes green so that they will match the dress that Matthew Ross gave her.
  • In the later seasons of Babylon 5, Lyta Alexander's eyes would turn solid black whenever she made use of the Vorlon enhancements to her psychic abilities. However she became even more powerful in the Postscript Season, she acquires Glowing Eyes of Doom instead. Possibly because the black contacts used for the old effect were painful to wear.
  • Buffy the Vampire Slayer:
    • Whenever Willow makes intensive use of magic, her eyes abruptly turned pitch-black while closed. Then, in the series finale, when using the scythe to activate all the potential slayers, her eyes (and hair) turn white, hinting she is using powerful white magic.
    • When Willow buffs up Buffy with magic to fight Adam, Buffy's eyes turn gold/yellow.
  • Doctor Who:
    • Leela's eyes are bleached permanently blue by a blinding explosion in "Horror of Fang Rock". Even though her vision later returns, her eye colour does not. This was a Written-In Infirmity (the actress hated the brown coloured contacts she had to wear as Leela and the production team decided to give her a break) but serves as something of a symbolic coming-of-age moment for her character, as the Doctor Pygmalioning her into a protegée has strikingly blue eyes.
    • When Rose absorbs the Heart of the TARDIS and becomes the Bad Wolf, her eyes turn golden. The same happens to the Moment when it assumes her human aspect.
    • The Ood gain Red Eyes, Take Warning whenever something else is directly controlling them. We eventually find the red eyes just represents their psychic network in action and normally isn't a sign of danger. In a much later episode, an Ood possessed the villain of the week has his eyes turn green.
  • In Fate: The Winx Saga, whenever the fairies use their powers, their eyes change color according to the element they possess (fire fairies get red-orange eyes, water fairies get steel blue eyes, mind fairies get purple eyes, and so forth).
  • In Forever Knight, vampires' eyes turn golden when they vamp out.
  • The Incredible Hulk (1977): When viewers see David's eyes turn green, it's confirmation that things are about to get smashed...
  • In the Kamen Rider franchise, the big, insectlike eyepieces of the Riders often change with the mode the suit is in. In a more sinister vein, they can also change with the mentality of the wearer if the powers present a hazard to his sanity (if a power-up is potentially a Superpowered Evil Side, and the Rider's eyepieces turn the color that represents that power source, you wanna be a few dozen counties over.)
  • Jekyll and Hyde (2015): Robert Jekyll's eyes flash bright blue whenever he is bordering on or fully transforming into Hyde.
  • In Legion, Lenny's eyes are brown during her first life, but blue when she comes Back from the Dead, a fact that even throws Ptonomy, a mutant with perfect recall. It turns out that this is because she's in the body of David's murdered sister Amy, which has been reshaped to look like the old Lenny.
  • In Merlin, Merlin's eyes turn brownish-gold when he uses magic.
  • In the Star Trek: The Original Series episode "Where No Man Has Gone Before" Gary Mitchell and Elizabeth Dehner both develop inhuman silver-colored eyes after the "energy barrier at the edge of the Galaxy" gives them a variety of psychic and telekinetic abilities.
  • Supernatural
    • Solid-coloured eyes are used to show demonic possession. Showing them, rather than the natural eye colour, is voluntary for the demon so it is used for shock value (both in universe and for the audience). Low-level demons use black; more powerful ones get more colourful options such as yellow or white.
    • Angels will sometimes change the eye color of their vessel's body to a bright blue. Notably in season nine, Sam's eyes glowed blue when Gadreel took over, so it was easier for Dean (and the audience) to know who he was talking to. Though his vessel's eyes are blue to begin with, Castiel tends to pull out the glowy version as an intimidation tactic.
  • Zig-zag: On a 1974 telecast of the game show Tattletales, panelist Harvey Korman represented the blue section and liked it since he said his podium matches his eyes. Guest host Gene Rayburn looked closer and said Harvey's eyes were green. Harvey, in Paul Lynde voice spluttered, "Oh, go away! They're blue!"
    Harvey Korman: (aside) Why am I talking like Paul Lynde??
  • Eye color is a key part of the werewolf mythology in Teen Wolf. Alphas have red eyes, and betas have either orange or blue eyes.
  • At the end of the series finale Daredevil (2015), Agent Ben Poindexter is undergoing a risky experimental procedure so he can walk again, which is shown to have caused his iris to change into a Bullseye pattern.

    Video Games 
  • In Warcraft elf eyes operate this way. Their eyes are pupilless, and glowy. Depending on the type of magic they are surrounded with, their eyes are different colors (different colors are habitually associated with the different types of magic). This is the only physical difference between the High Elves and the Blood Elves, who are actually just factions with different ideologies and not different races. High Elves have blue eyes since they cut themselves off from the corrupted Sunwell. Blood Elves have green eyes reflecting the corruption of the Sunwell, although some are starting to have golden eyes now that the Sunwell has been restored. Night Elves normally have silver eyes, although rare males are born with golden eyes which they believe marks them for a special destiny (at least in the case of Illidan Stormrage, this seems to be true). Nightbourne meanwhile have lavender eyes, reflecting the Nightwell's peculiarly colored magic.
    • The Undead sort of fall into this trope: though in their case it's more that their eyes are missing entirely. Same for the Demon Hunters. The color comes from the magic that they are filled with. In something of a subversion, this doesn't particularly say anything about their philosophical inclinations however.
    • Canonically, if a character is channeling a lot of magical power their eyes start to glow showing that the power has filled up their soul. The different magics have different philosophies associated with them, to some degree. Though not to the point where the type of magic someone wields indicates their political alignment or anything. But it is to the point where certain races either cannot or will not engage with certain types of magic.
  • When Faize from Star Ocean: The Last Hope gets subjected to a lot of stress, his LEGO Genetics causes him to unconsciously suppress it. This gets shown with his eyes turning red.
  • In Sonic the Hedgehog, Sonic's eyes are normally green, but when he goes Super Sonic, they turn red.
  • Tales Series
    • In Tales of Symphonia, Colette's blue eyes turn red when she loses her soul; they return to blue when she gets it back again. In the anime adaptation her eyes turn green when she is possessed by Martel.
    • In Tales of Symphonia: Dawn of the New World, Emil's normally green eyes turn red whenever his "Ratatosk-mode" personality is in control (usually during battle only). When we first see him, his eyes are gray, because he hasn't invented a personality yet.
  • In Xenosaga KOS-MOS's normally red eyes turn blue when the hidden soul of Mary Magdalene-yes, THAT Mary Magdalene-takes over her body. Notably, they turn blue when she uses the hiterto unknown X-Buster to absorb the Gnosis, when she saves the Elsa from burning up in the atmosphere, and two times when she saved Shion and Allen, Shion only finding out about this part of KOS-MOS the second rescue.
  • Danganronpa: Trigger Happy Havoc's Fukawa has eyes that change from a soft pinkish-grey to bright red when her Split Personality Genocider Syo is in charge.
  • Throughout Kingdom Hearts, eyes change color to an orange-gold whenever someone gets too close to the darkness, or if they're a vessel for Xehanort.
    • Braig's eyes change from brown to gold, after he becomes part-Xehanort.
    • Terra's eyes go from blue to orange when Master Xehanort possesses him.
    • Xehanort's eyes go from orange to brown and back again during the year he spends amnesiac.

    • Yang has violet coloured eyes under normal circumstances. However, when she gets angry, her eyes turn a vivid shade of red. It's also a sign that her Semblance is active, but she normally only activates her Semblance whenever she's angry. Her father has baby blue eyes and her mother has vivid red eyes, so her default violet eyes are mid-way in colour between her parents, while her vivid red transformation makes her look very similar to her mother.
    • Neopolitan has tri-coloured hair. The left half is brown, the right half pink with white streaks. Her eyes usually default to a pink right eye and brown left eye. However, when she's fighting, her eyes will flit between different colours: pink left, brown right; two pink; two brown. When she fled Raven, she was clearly distressed and afraid, and her eyes turned vivid white. During the tournament, she disguises herself twice - once as a student, once as a medic. As a student, she has black hair and green eyes, while as a medic, she has black hair and purple eyes. While her hair colour and clothing seem connected to her illusion powers, her eye colour changes seem to be something else.
    • Oscar is the first character introduced with heterochromia iridum; his eyes are predominantly green, but a faint yellow circle borders the pupils and the green irises contain a segment of solid brown. He has the ability to do what Qrow describes as a "parlour trick"; upon activating the ability, the yellow bordering his pupils flash, visibly filling his irises with a solid gold that flares like light before appearing to fade back to their normal colour. However, for as long as the ability is active, his reflection will reveal that his eyes are still solid gold. Ozpin was cursed thousands of years ago to walk the earth for as long as Salem remains a threat; instead of dying, his soul, Aura, memories and abilities hop to a new host. Oscar is Ozpin's latest host and the brown speck in his green eyes is the same shade as Ozpin's brass-coloured eyes; when he lets Ozpin take control of his body, his body pulses and his eyes turn gold.

    • Heartful Punch actually subverts this — unlike most girls, she was born with the cyan eyes she now has as a magical girl. This is because she was born to an active magical girl, and as a result, her mother's power was passed down to her.
  • The Sword Interval: Heroine Fall Barros was attacked by the Hierophant when she was twelve years old, and given Supernatural Gold Eyes as a result. This is actually a subversion.
