Shadowy Kikyo

#510f56
Notes

Shadowy Kikyo (#510F56) is a deep violet 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 (296°, 70%, 20%) 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 green. 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.

Kikyo
noun

Japanese 桔梗, the balloon flower (Platycodon grandiflorus) — a wild perennial of Japanese mountainsides whose star-shaped corolla unfurls from an inflated bud. The flower is one of the Seven Autumn Flowers of classical waka poetry. Kikyo color refers to a fully unfurled Platycodon grandiflorus corolla: a saturated, slightly cool deep violet with the velvet finish of fresh balloon-flower petals.

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.
