Trim Heaven
Trim Heaven (#01BFCB) 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 (184°, 99%, 40%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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
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.
The vault of the sky and (in religious vocabulary) the realm of the divine — and the saturated blue used in medieval European religious painting for sky, Mary's mantle, and divine background. Heaven color refers to a Florentine Annunciation azure background: a saturated, slightly cool deep blue with the matte finish of ultramarine pigment in tempera.
