Neat Coy Peacock

#127973
Notes

Neat Coy Peacock (#127973) is a deep cyan with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (177°, 74%, 27%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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

Neat
adjective

Old French net, clean / pure — sharing root with Latin nitidus. As a color modifier, neat implies a clear-and-orderly quality where the hue carries the well-arranged visual register without clutter or excess. Sits at the crisp-and-orderly end of the grid, parallel to trim and tidy in usage.

Coy
modifier

Latin quietus, still-and-quiet. As a color modifier, coy implies a shy-and-reserved-and-half-glanced quality, the visual register of Watteau-fête-galante-and-Rococo-coy hand-shy-and-reserved-and-half-glanced Watteau-fête-galante-and-Rococo-and-French-pastoral coyed-and-shy-and-reserved-and-half-glanced surfaces under Watteau-fête-galante-and-Rococo-and-French-pastoral garden-pavilion-and-fan-and-mask powdered-pastel-light. Sits at the modifier-and-mood end of the grid, parallel to meek and charm in usage.

Peacock
noun

Pavo cristatus, the Indian peafowl whose male displays the most elaborate sexual ornament in birds — a fan of two-meter eyespotted tail feathers in iridescent blue-green. The color is structural, not pigmented: created by interference patterns in the feather barbules. Peacock blue refers to the dominant body color: a saturated, slightly muted teal-blue with the optical depth of structural color. Cooler than persian, warmer than sapphire.
