Pleasant Horus Peacock

#0c729d
Notes

Pleasant Horus Peacock (#0C729D) 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 (198°, 86%, 33%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Pleasant
adjective

From the French plaisant, pleasing — used as a color modifier since the fifteenth century for hues that read as agreeable, the kind of color that wears well over a long viewing without becoming demanding or fatiguing. Pleasant green, pleasant rose: moderate saturation combined with optical comfort. Sits at the crisp-bucket alongside easy and calm.

Horus
modifier

Egyptian Heru, falcon-headed-sky-god. As a color modifier, horus implies a falcon-headed-and-Eye-of-Horus quality, the visual register of Egyptian-Horus-and-Edfu-temple hand-falcon-headed-and-Eye-of-Horus Egyptian-Horus-and-Edfu-temple-and-falcon-pharaoh horus-and-falcon-headed-and-Eye-of-Horus surfaces under Egyptian-Horus-and-Edfu-temple-and-falcon-pharaoh Edfu-Aswan-temple-and-falcon-throne falcon-eye-light. Sits at the modifier-and-myth end of the grid, parallel to isis and thoth 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.
