Infernal Toucan

#5b2311
Notes

Infernal Toucan (#5B2311) is a deep orange 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 (15°, 69%, 21%) 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 cyan. 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.

Toucan
noun

The family Ramphastidae — tropical American birds with oversized colorful beaks. Toucan refers specifically to the keel-billed toucan (Ramphastos sulfuratus) whose beak is colored in green, yellow, orange, and red. The color refers to the orange section of a toucan's beak: a saturated, slightly red orange with the matte finish of keratin. Warmer than oriole.
