Trim Cardoon

#20b4aa
Notes

Trim Cardoon (#20B4AA) 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 (176°, 70%, 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 red. 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.

Cardoon
noun

Cynara cardunculus, the Mediterranean thistle — relative of the globe artichoke (C. cardunculus var. scolymus) — with deeply lobed silver-green foliage and architectural form. The color refers to mature cardoon foliage in a kitchen garden: a soft, slightly cool silver-green-blue with the matte finish of large pinnately lobed leaves.

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.
