Infernal Cornwall

#123a0c
Notes

Infernal Cornwall (#123A0C) is a deep green 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 (112°, 66%, 14%) 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 violet. 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.

Cornwall
noun

The southwestern English county — and the rolling green hills of Cornish moors and the Cornish Heritage Coast hedgerows. Cornwall color refers to a Cornish hillside in late spring: a saturated, slightly cool deep yellow-green with the matte finish of grazed pasture grass. Drier than verdant.
