Fizzy Limpid

#04cefb
Notes

Fizzy Limpid (#04CEFB) 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°, 97%, 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

Fizzy
adjective

Imitative-onomatopoeic origin — adjectival suffix -y, evoking the sound of carbonation. As a color modifier, fizzy implies a saturated-and-effervescent-and-bubbly quality, the bright color of Champagne-and-Prosecco effervescent-wine carbonation-bubble-light reflection. Sits at the bright-and-effervescent end of the grid, parallel to bubbly and sparkling in usage.

Limpid
noun

An adjectival noun meaning clear and untroubled — used for the soft pale-blue of perfectly transparent water. Limpid color refers to a limpid alpine lake at dawn before any wind: a soft, slightly cool pale blue with the optical clarity of unperturbed water.

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.
