Tomblike Cinnabar

#73021f
Notes

Tomblike Cinnabar (#73021F) 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 (345°, 97%, 23%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary teal. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Tomblike
adjective

Greek tymbos, tomb — adjectival suffix -like. As a color modifier, tomblike implies the deep-and-funereal-and-sepulchral quality of Etruscan-and-Egyptian rock-cut royal-tomb interiors, particularly the Valley-of-the-Kings and Cerveteri-necropolis hand-carved chamber-painting walls. Sits at the deep-and-funereal end of the grid, parallel to sepulchral and crypted.

Cinnabar
noun

Mercury sulfide crystallized in volcanic veins, ground into pigment for at least four millennia. The red of Pompeian frescoes, Chinese imperial seals, the carved cinnabar lacquerware of the Ming dynasty. Toxic to grind — the mines of Almadén in Spain killed slaves and convicts for centuries — and dazzling to behold: the brilliant scarlet that gave its name to a color and a warning to apprentices.
