Cellared Crocus

#3a1d7d
Notes

Cellared Crocus (#3A1D7D) 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 (258°, 62%, 30%) 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Cellared
adjective

Latin cellārium, storehouse — past-participle of cellar. As a color modifier, cellared implies the deep-and-cool-and-architectural quality of Bordeaux-and-Burgundy wine-cellar underground stone-and-oak storage-chamber, with the patina of multi-decade barrel-aging-and-bottle-laying. Sits at the deep-and-architectural end of the grid, parallel to crypted with viticulture register.

Crocus
noun

The genus Crocus — small autumn or spring corms that flower before their leaves emerge, push through snow in March, and include C. sativus, the source of saffron. The color refers to a fresh blue-violet spring crocus: a saturated, slightly violet-shifted deep blue with the satiny finish of a six-petaled cup catching morning light. Cooler than amethyst, warmer than iris, with the seasonal weight of a flower that arrives weeks before everything else.

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.
