Clear Keel Mint

#528f68
Notes

Clear Keel Mint (#528F68) is a true green 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 (142°, 27%, 44%) places it in the muted 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Clear
adjective

From the Latin clarus, bright, distinct — used as a color modifier since the medieval period for hues without haze or mixing. Clear blue sky, clear green water: the implication is moderate saturation combined with optical clarity. Sits at the crisp-bucket center alongside clean and true.

Keel
modifier

Old Norse kjölr, keel. As a color modifier, keel implies a longitudinal-bottom-spine-of-ship quality, the visual register of Tall-Ship-and-Royal-Navy-Keel hand-laid longitudinal-bottom-spine timber-and-iron-keel tall-ship-and-frigate maritime-architecture surfaces under hull-and-keel maritime hull-bottom light. Sits at the modifier-and-nautical end of the grid, parallel to hull and spar in usage.

Mint
noun

The genus Mentha — peppermint, spearmint, apple mint, water mint — the cooling herb whose menthol gives it that quality at the molecular level. The color refers to fresh peppermint leaves before drying: a clean, slightly cool green with the matte finish of trichome-rich leaf surface. Lighter than basil, cooler than parsley, with the mojito-and-Pimm's association of a herb tied to summer drinks across two continents.

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.
