Truthful Lazuli

#2b606e
Notes

Truthful Lazuli (#2B606E) is a deep cyan 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 (193°, 44%, 30%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Truthful
adjective

Old English trēowth, truth — adjectival suffix -ful. As a color modifier, truthful implies a clear-and-honest-and-direct quality where the hue carries the visual register of accurate-and-faithful-representation declaration. Sits at the crisp-and-honest end of the grid, parallel to candid and honest in usage.

Lazuli
noun

Passerina amoena, the lazuli bunting — a North American songbird whose males display saturated deep-blue plumage with white wing bars and chestnut breasts. Named for the gemstone (lapis lazuli) the bird's plumage resembles. The color refers to a male lazuli bunting in breeding plumage: a saturated, slightly cool deep blue.
