Trim Kyanite

#4b9199
Notes

Trim Kyanite (#4B9199) is a true cyan with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (186°, 34%, 45%) 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.

Kyanite
noun

An aluminum silicate mineral — named for the Greek kyanos (deep blue), the same root as cyan. Mined principally in Brazil, India, and the United States. The color refers to a polished Brazilian kyanite blade: a saturated, slightly cool deep blue with the satin finish of fibrous-bladed silicate.
