Infernal Rose

#2b0a0a
Notes

Infernal Rose (#2B0A0A) is a deep red 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 (0°, 62%, 10%) 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.

Rose
noun

The Latin rosa, the Greek rhodon, the Persian gul — every European language has a different name for the same flower and the same color. Rose covers the spectrum from blush to fuchsia depending on the cultivar, but in pigment shorthand it means a cool, slightly bluish red — the inside of a damask petal, the dye that washes out of madder root.
