Regal Kohbai

#a52689
Notes

Regal Kohbai (#A52689) is a true magenta with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (313°, 63%, 40%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Regal
adjective

Latin rēgālis, kingly — derived from rēx (king). As a color modifier, regal implies a saturated-and-royal-formality quality, the deep-rich color of British-Coronation-period royal vestment-and-mantle and Imperial-State-Crown regalia. Sits at the bold-and-imperial end of the grid, parallel to sovereign and royal in usage.

Kohbai
noun

Japanese 紅梅, red plum-blossom (Prunus mume var. kohbai) — the deep-pink-flowered cultivar of Japanese plum, a traditional New Year color in Heian-period kasane no irome layered silks. Kohbai color refers to a fully bloomed kohbai plum branch in February: a saturated, slightly cool deep magenta with the velvet finish of fresh plum-blossom petals against bare branches in early-spring snow.
