Infernal Glicine

#1d1b5e
Notes

Infernal Glicine (#1D1B5E) is a deep blue with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (242°, 55%, 24%) 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

Infernal
adjective

Latin infernālis, of the lower realms — derived from infernus (underworld). As a color modifier, infernal implies the deep-glowing-furnace-darkness of Dante-Inferno-and-Bosch-tryptich infernal imagery, with the warm undertone of fire-light against shadow. Sits at the deep-and-warm end of the grid, parallel to hellish and warmer than Hadean.

Glicine
noun

Italian for Wisteria sinensis, the cascading purple-violet flowering vine introduced from China to European gardens in 1816. Glicine color refers to a fully bloomed Glicine raceme on a Tuscan pergola: a saturated, slightly cool deep blue-violet with the velvet finish of dense pendulous wisteria racemes. Stocks as a fashion-color name in early-20th-century Italian millinery and Liberty-style enamels.
