Rich Adonis

#a43b3f
Notes

Rich Adonis (#A43B3F) is a true red with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (358°, 47%, 44%) 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Rich
adjective

Old French riche, wealthy, abundant — applied to color since the medieval period for hues that read as plentiful in pigment. Rich red, rich brown: the implication is depth combined with saturation, a color that gives the eye more to absorb. Sits at the saturated mid-light corner of the engine's grid, slightly warmer than bold and deeper than vivid.

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.

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.
