Velvety Adonis

#a10a04
Notes

Velvety Adonis (#A10A04) is a deep red 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 (2°, 95%, 32%) 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Velvety
adjective

An adjectival form of velvet, used since the eighteenth century for colors that read as if they had the matte light-absorbing quality of velvet. Implies high saturation combined with a non-glossy surface — the matte richness of a deep wine in a fabric rather than in a glass. Sits in the bold-and-deep corner of the grid alongside plush and lush.

Adonis
noun

Adonis annua, the small wild buttercup of European meadows — also called pheasant's eye — with single deep red flowers and dark centers. Named for the Greek mythological youth whose blood, in Ovid's telling, sprouted the flower. The color refers to a fresh Adonis bloom in late spring: a saturated, slightly cool deep red with the matte finish of a six-petaled wild flower. Deeper than coral.
