Colours in photographs vary with lighting, material, camera processing and screen calibration — the named colours below are visual approximations, not exact measurements.

The radiating fibrous structure visible here is the iris's real anatomy — the yellow-green flecking near the pupil and the blue-teal further out are two genuinely different regions, not a single uniform colour.
Extreme close-up eye photography like this is very often colour-enhanced or saturation-boosted in editing — treat this as an illustrative, vivid example of blue-green iris structure, not an unedited, exact colour reference. A camera can never capture eye colour perfectly neutrally in any case, since white balance and exposure both shift what's recorded."Eye I" by Thomas Tolkien, CC BY 2.0, via Wikimedia CommonsThe same simultaneous-contrast effect that makes a grey square look different against different-coloured backgrounds also applies to eye colour: a nearby clothing colour can make eyes look more or less vivid, or shift their apparent warmth, without the eyes themselves changing at all.
In practice: If eye colour looks unusually vivid or muted in a particular outfit, the clothing colour beside the face is a common, ordinary explanation — not a change in the eyes themselves.

Complementary
Opposite hues (180° apart) for maximum hue contrast.
Analogous
Neighbouring hues on the colour wheel for a low-contrast, harmonious feel.

For an accessible, low-contrast-risk pairing, monochromatic (same-hue) combinations are usually the safest starting point — see the harmonies above.
Worked out from this colour’s own measurements — its lightness, saturation and undertone — rather than written for it. That is why the guidance differs from one colour to the next even when the two look similar.
This works across a range of sizes. At chroma 30 it is assertive enough to register on a small object and restrained enough not to dominate a wall.
Chroma 30 sits inside the range walls and large surfaces carry without taking over the room.
Chroma 30 sits inside the range secondary surfaces carry without taking over the room.
Chroma 30 sits inside the range furniture carry without taking over the room.
Chroma 30 sits inside the range rugs, curtains and bedding carry without taking over the room.
Chroma 30 sits inside the range trim and joinery carry without taking over the room.
Chroma 30 is exactly what an accent is for. The saturation that makes this difficult across a wall is the reason it works on a cushion, a door or a single chair.
Chroma 30 is strong enough to register and restrained enough to repeat. Two or three appearances read as intentional where one reads as an orphan.

Opposed in undertone to Oak without much else to explain the difference, which is the combination the eye most often reads as an error. The amount of timber matters as much as the tone: one piece is an accent, a floor plus joinery is the room's dominant colour.
Opposite in undertone to Walnut, and separated enough in hue that the difference reads as deliberate contrast rather than as a clash. The amount of timber matters as much as the tone: one piece is an accent, a floor plus joinery is the room's dominant colour.
Opposite in undertone to Pine, and separated enough in depth that the difference reads as deliberate contrast rather than as a clash. The amount of timber matters as much as the tone: one piece is an accent, a floor plus joinery is the room's dominant colour.
Opposed in undertone to Plywood without much else to explain the difference, which is the combination the eye most often reads as an error. The amount of timber matters as much as the tone: one piece is an accent, a floor plus joinery is the room's dominant colour.
Opposite in undertone to Light wood (ash, birch, beech), and separated enough in depth that the difference reads as deliberate contrast rather than as a clash. The amount of timber matters as much as the tone: one piece is an accent, a floor plus joinery is the room's dominant colour.
Opposite in undertone to Dark wood, and separated enough in hue that the difference reads as deliberate contrast rather than as a clash. The amount of timber matters as much as the tone: one piece is an accent, a floor plus joinery is the room's dominant colour.
Opposite in undertone to Reddish wood (mahogany, cherry, teak), and separated enough in hue that the difference reads as deliberate contrast rather than as a clash. The amount of timber matters as much as the tone: one piece is an accent, a floor plus joinery is the room's dominant colour.
Shares Brass's cool bias, so the two agree about the temperature of the room. They sit close in depth, so expect a quiet, tonal relationship rather than a contrast. Metal carries more attention than its area suggests, so repetition matters more than the exact finish.
Shares Gold-tone's cool bias, so the two agree about the temperature of the room. They sit close in depth, so expect a quiet, tonal relationship rather than a contrast. Metal carries more attention than its area suggests, so repetition matters more than the exact finish.
Shares Chrome's cool bias, so the two agree about the temperature of the room. There is also 32 points of lightness between them, which keeps the two readable as separate elements. Metal carries more attention than its area suggests, so repetition matters more than the exact finish.
Shares Stainless steel's cool bias, so the two agree about the temperature of the room. There is also 28 points of lightness between them, which keeps the two readable as separate elements. Metal carries more attention than its area suggests, so repetition matters more than the exact finish.
Shares Black metal's cool bias, so the two agree about the temperature of the room. There is also 41 points of lightness between them, which keeps the two readable as separate elements. Metal carries more attention than its area suggests, so repetition matters more than the exact finish.
Shares Copper's cool bias, so the two agree about the temperature of the room. They sit close in depth, so expect a quiet, tonal relationship rather than a contrast. Metal carries more attention than its area suggests, so repetition matters more than the exact finish.
Name origin
Inherited from the cyan hue family, not specifically documented about this exact shade — see methodology.
Calculated directional adjustments. Some directions converge on the same result from this starting colour — shown as one merged card with an explanation, not repeated duplicates. Generated shades link to a curated profile only when one is close enough.

Warmer & Greener & Redder & Yellower
Hue rotated toward warm (red/orange) From this starting colour, moving warmer and greener and redder and yellower converges on the same calculated result.
Cooler & Bluer
Hue rotated toward cool (blue) From this starting colour, moving cooler and bluer converges on the same calculated result.
