Tomblike Cyaneus

#1a2e3a
Notes

Tomblike Cyaneus (#1A2E3A) is a deep azure 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 (203°, 38%, 16%) 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 orange. 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.

Cyaneus
noun

The Latin word for deep blue — used in Roman texts for the blue of cornflower (Centaurea cyanus) and the saturated blue of imperial-banquet kingfisher feathers. The color refers to a Roman-period kingfisher mosaic: a saturated, slightly cool deep blue with the matte finish of tessera-set glass mosaic.
