Phosphoric Fiji

#37f8d5
Notes

Phosphoric Fiji (#37F8D5) 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 (169°, 93%, 59%) 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

Phosphoric
adjective

Greek phōsphóros, light-bringer — adjectival suffix -ic. As a color modifier, phosphoric implies a saturated-and-cool-glow quality, the bright color of match-tip-strike and firefly phosphorus-emission luminescence. Sits at the bright-and-cool end of the grid, parallel to phosphorescent and fluorescent in usage.

Fiji
noun

The Melanesian archipelago — and the saturated turquoise of Fijian lagoons surrounding the Yasawa and Mamanuca island groups. Fiji refers to a Fijian lagoon at high tide: a saturated, slightly cool deep blue-green with the optical clarity of warm South Pacific water.

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.
