Phosphorescent Spearmint

#12e2b7
Notes

Phosphorescent Spearmint (#12E2B7) is a true teal with a neon character. It sits at the high-saturation edge of its family. Use it sparingly, as signage, accent, or highlight against darker surfaces. Its HSL profile (168°, 85%, 48%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Phosphorescent
adjective

Greek phōsphóros, light-bringer — adjectival suffix -escent. As a color modifier, phosphorescent implies a saturated-and-cool-glow-after-stimulation quality, the bright cool-green-blue color of Cu-doped-ZnS glow-in-the-dark photoluminescent surfaces. Sits at the bright-and-cool end of the grid, parallel to fluorescent and luminous in usage.

Spearmint
noun

Mentha spicata, the mild green mint of Mediterranean kitchens — the lamb-sauce mint of British cooking, the mojito mint of Cuba, the karkadeh tea garnish of Egypt. The color refers to fresh spearmint leaves: a saturated, slightly cool green with the matte finish of trichome-rich foliage. Brighter than peppermint, lighter than basil, with the lighter aromatic profile of carvone instead of menthol.
