Shadowy Akane

#280a18
Notes

Shadowy Akane (#280A18) 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 (332°, 60%, 10%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary teal. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Shadowy
adjective

Old English sceaduwig, full of shadow — adjectival form of shadow. As a color modifier, shadowy implies a deep-and-obscured quality where the hue is partially-occluded by intervening shade. Sits at the deep-and-veiled end of the grid, parallel to shaded and cloaked in usage.

Akane
noun

Rubia cordifolia, the Asian madder root that gave its name in Japanese to a saturated dawn-red color and to one of the oldest dyes in continuous use in Japan. Akane has dyed temple textiles, kimono linings, and the akabō porter caps of pre-modern Tokyo for over a thousand years. The color refers to a freshly akane-dyed silk: a saturated, slightly orange-shifted red with the plant-dye warmth of natural pigment.
