Squared Larimar

#53dad3
Notes

Squared Larimar (#53DAD3) 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 (177°, 65%, 59%) 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

Squared
adjective

Latin quadrātus, four-sided — past-participle of square. As a color modifier, squared implies a clear-and-rectilinear-and-orthogonal quality where the hue carries the visual register of right-angle architectural-and-grid alignment. Sits at the crisp-and-balanced end of the grid, parallel to aligned and plumb in usage.

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.
