Charred Chionodoxa

#311d81
Notes

Charred Chionodoxa (#311D81) is a deep indigo 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 (252°, 63%, 31%) 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 yellow. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Charred
adjective

The past participle of char, to burn slightly — and a color word for surfaces that have been heat-blackened without fully consuming. Charred implies the carbon-blackened skin of grilled meat, fired wood, or smoke-darkened cathedral stone. Sits in the deep-and-near-black end of the engine's grid, slightly drier than inky and warmer than somber.

Chionodoxa
noun

Mediterranean Glory-of-the-Snow (Chionodoxa luciliae) — a small Anatolian-mountain spring-flowering bulb whose name combines Greek khión (snow) and dóxa (glory). Chionodoxa color refers to a freshly opened Chionodoxa luciliae six-tepalled star: a saturated, slightly cool deep blue-violet with the velvet finish of small radiating tepals around a paler center. Blooms while alpine snow lingers in patches.

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.
