Spectral Lithodora

#24bbee
Notes

Spectral Lithodora (#24BBEE) is a true cyan 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 (195°, 86%, 54%) 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

Spectral
adjective

Latin spectrum, appearance — adjectival suffix -al. As a color modifier, spectral implies a saturated-and-rainbow-decomposed-and-pure quality, the bright color of Newton-prism sunlight-decomposed seven-color spectrum band. Sits at the bright-and-pure end of the grid, parallel to prismatic and pure in usage.

Lithodora
noun

The genus Lithodora — Mediterranean rock-garden ground covers with intensely deep-blue flowers. L. diffusa 'Heavenly Blue' is among the most saturated blue flowers grown in temperate gardens. The color refers to a fresh L. diffusa mat in flower: a saturated, slightly cool deep blue with the matte finish of small five-petaled flower.

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

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.
