Clean Larimar

#40c1e4
Notes

Clean Larimar (#40C1E4) is a true cyan with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (193°, 75%, 57%) 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

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.

Larimar
noun

A blue variety of pectolite — a calcium-sodium silicate — found only in one mountain range in the Dominican Republic. Marketed as a gemstone since the 1970s and named after a Spanish word for the sea. The color refers to a polished larimar cabochon: a soft, slightly muted light blue with the cloudy translucency of pectolite. Lighter than aqua, warmer than glacier, with the gem-trade specificity of a stone that occurs in exactly one place on Earth.
