Crisp Tropics
Crisp Tropics (#0FAC4B) is a true green with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (143°, 84%, 37%) 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin crispus, curled — drifted in English from the curled hair sense to fresh and clean. As a color modifier, crisp implies saturation combined with optical clarity, with no haze or film between the eye and the surface. Used across the bright and crisp buckets where the hue is fresh-looking. Slightly less assertive than vivid.
The Earth's equatorial belt between the Tropic of Cancer and the Tropic of Capricorn — the region of the world where the sun reaches direct overhead at some point of the year. Tropics refers to the unifying blue-green of tropical-zone ocean and lagoon water: a saturated, slightly cool deep blue-green.
