Phosphorescent Camas

#0598f8
Notes

Phosphorescent Camas (#0598F8) is a true azure 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 (204°, 96%, 50%) 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 orange. 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.

Camas
noun

The genus Camassiacamas lily, North American native bulbs whose deep-blue flower spikes were a staple food source for Pacific Northwest Indigenous peoples (the bulbs are cooked in pit ovens). The color refers to a C. quamash meadow at peak bloom: a saturated, slightly cool deep blue with the satin finish of six-petaled lily-form flower.

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.
