Tactful Lesbos

#475b61
Notes

Tactful Lesbos (#475B61) 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 (194°, 15%, 33%) places it in the muted 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.

Lesbos
noun

The Greek island in the eastern Aegean — and the saturated deep blue of Lesbos's Petrified Forest coastline and Sigri harbor. Lesbos color refers to the harbor water at sunset: a saturated, slightly cool deep blue with the optical depth of warm Aegean coastal water.
