Clean Corona Mint

#99fef0
Notes

Clean Corona Mint (#99FEF0) is a soft teal with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (172°, 98%, 80%) places it in the highly saturated band at a light 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

Clean
adjective

Old English clǣne, pure, free of dirt — used as a color modifier since the medieval period for hues that read as crisp and uncontaminated by other pigments. Clean white, clean blue: moderate saturation combined with optical clarity. Sits at the crisp-bucket center alongside clear and true.

Corona
modifier

Latin corona, crown-or-circle-of-light. As a color modifier, corona implies a sun-corona-and-eclipse-halo quality, the visual register of total-solar-eclipse-corona hand-sun-corona-and-eclipse-halo total-solar-eclipse-and-Sun-corona-and-Bailey's-Beads corona-and-sun-corona-and-eclipse-halo surfaces under total-solar-eclipse-and-Sun-corona-and-Bailey's-Beads totality-and-Moon-shadow-and-pearl ring-of-fire-light. Sits at the modifier-and-cosmic end of the grid, parallel to prism and nebula 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.
