Robust Andaman

#33a558
Notes

Robust Andaman (#33A558) is a true 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 (139°, 53%, 42%) 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Robust
adjective

From the Latin robustus, of oak — implying strength combined with substance. As a color modifier, robust describes saturation combined with body: a robust burgundy, a robust olive. Sits in the bold-and-warm corner alongside strong and solid, with the slightly textural implication of a color that has substance behind the pigment.

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.
