Calm Andaman

#309f86
Notes

Calm Andaman (#309F86) is a true teal 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 (166°, 54%, 41%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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

Calm
adjective

Latin calma, heat of the day — paradoxically drifted in Italian to mean stillness. Used as a color modifier since the seventeenth century for hues that read as untroubled. Calm blue, calm gray: moderate saturation combined with optical quiet. Sits at the crisp-bucket near quiet and steady.

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.
