Trim Cycladic

#51b2da
Notes

Trim Cycladic (#51B2DA) 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 (198°, 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Trim
adjective

Old English trymman, to make firm — sharing root with firm. As a color modifier, trim implies a clear-and-neatly-arranged quality where the hue carries the visual register of carefully-edited surface-detail. Sits at the crisp-and-neat end of the grid, parallel to neat and tidy in usage.

Cycladic
noun

Of the Cyclades, the Greek archipelago — and the saturated blue of Cycladic-island cupolas, painted blue-and-white church domes, and the deep Mediterranean water of Mykonos, Santorini, Naxos. Cycladic color refers to a Cycladic church dome against the sea: a saturated, slightly cool deep blue with the matte finish of limewash-and-cobalt paint.

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.
