Tomblike Heki

#1f2f6e
Notes

Tomblike Heki (#1F2F6E) is a deep blue with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (228°, 56%, 28%) 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 amber. 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.

Heki
noun

Japanese heki (碧) — a classical Sino-Japanese character spanning jade-green and deep-blue in pre-modern color vocabulary. Heki-iro names the saturated blue of polished imperial-grade nephrite. The color refers to a polished Japanese nephrite yu disc: a saturated, slightly cool deep blue-green with the satin finish of fine jade.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
