Radiant Chiton Turquoise

#3ce3d5
Notes

Radiant Chiton Turquoise (#3CE3D5) is a true cyan with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (175°, 75%, 56%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Radiant
adjective

From the Latin radiare, to emit rays — used as a color word since the seventeenth century for hues that read as luminous and emitting. Radiant gold, radiant pink: the implication is high luminance combined with the optical impression of an outward light. Sits in the bright-bucket center alongside glowing.

Chiton
modifier

Greek χιτών, Hellenic-tunic. As a color modifier, chiton implies a Hellenic-tunic-and-pinned-and-pleated quality, the visual register of Hellenic-Doric-and-Ionic-chiton hand-Hellenic-tunic-and-pinned-and-pleated Hellenic-Doric-and-Ionic-chiton-and-Phidias-Parthenon chiton-and-Hellenic-tunic surfaces under Hellenic-Doric-and-Ionic-chiton-and-Phidias-Parthenon Athenian-Acropolis-and-Hellenic-court Hellenic-tunic-light. Sits at the modifier-and-textile end of the grid, parallel to peplos and tunic in usage.

Turquoise
noun

The hydrated copper-aluminum phosphate mined in Persia and the American Southwest for thousands of years — the firuze of Iran, the chalchihuitl of Mesoamerica, the heart of Pueblo and Navajo silverwork. The color refers to a fine Sleeping Beauty turquoise from Arizona: a saturated, slightly green-shifted blue with the slight matrix of host-rock veining. Brighter than persian, lighter than cerulean.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
