Organized Larimar

#28cec5
Notes

Organized Larimar (#28CEC5) 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°, 67%, 48%) 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

Organized
adjective

Greek órganon, instrument / tool — past-participle of organize. As a color modifier, organized implies a clear-and-coordinated-and-systematic quality where the hue carries the visual register of well-coordinated-and-classified arrangement. Sits at the crisp-and-orderly end of the grid, parallel to orderly and methodical 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.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
