Splashy Cyaneus

#01cffd
Notes

Splashy Cyaneus (#01CFFD) 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 (191°, 99%, 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Splashy
adjective

Imitative-onomatopoeic origin — adjectival suffix -y, evoking the sound of liquid impact. As a color modifier, splashy implies a saturated-and-attention-grabbing-and-bold quality, the bright color of Pop-Art-and-1950s-Tiki mid-century-modern showy-decor advertising-and-display. Sits at the bright-and-flamboyant end of the grid, parallel to showy and flamboyant in usage.

Cyaneus
noun

The Latin word for deep blue — used in Roman texts for the blue of cornflower (Centaurea cyanus) and the saturated blue of imperial-banquet kingfisher feathers. The color refers to a Roman-period kingfisher mosaic: a saturated, slightly cool deep blue with the matte finish of tessera-set glass mosaic.

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.
