Adamant Sakurairo

#890b6b
Notes

Adamant Sakurairo (#890B6B) is a deep magenta 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 (314°, 85%, 29%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Adamant
adjective

Greek adámas, unconquerable — derived from a- (not) plus damnan (to subdue). As a color modifier, adamant implies a saturated-and-rock-hard quality where the hue maintains diamond-hard pigmentation. Sits at the bold-and-resilient end of the grid, parallel to indomitable and ironclad in usage.

Sakurairo
noun

Japanese 桜色, cherry-blossom color (Prunus serrulata) — the iconic pale-pink hanami color whose deep saturated form occurs in the yaezakura double-petaled cultivars. Sakurairo color refers to a yaezakura double-cherry petal at peak bloom: a saturated, slightly cool deep magenta with the velvet finish of fresh saturated double-petaled cherry-blossom. Warmer than kohbai and cooler than momo (peach).

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.
