Trim Aqua

#337291
Notes

Trim Aqua (#337291) is a true azure 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 (200°, 48%, 38%) 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.

Aqua
noun

Latin for water, borrowed into English as a color name in the early twentieth century — initially for the pale blue-green of swimming pools and tropical seas. The color refers to a clear-bottomed swimming pool in midday sun: a clean, slightly green-shifted light blue with the optical clarity of filtered water. Cooler than seafoam, lighter than turquoise, with the mid-century weight of a word that paints itself across postwar interior decor.

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.
