Clean Andaman

#287840
Notes

Clean Andaman (#287840) is a deep green 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 (138°, 50%, 31%) 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Clean
adjective

Old English clǣne, pure, free of dirt — used as a color modifier since the medieval period for hues that read as crisp and uncontaminated by other pigments. Clean white, clean blue: moderate saturation combined with optical clarity. Sits at the crisp-bucket center alongside clear and true.

Andaman
noun

The Indian Ocean sea between the Malay Peninsula and the Andaman Islands — and the saturated blue-green of Andaman water at the Surin and Similan island groups. Andaman color refers to mid-depth Andaman Sea water: a saturated, slightly cool deep blue-green with the optical clarity of tropical Asian water.
