Fizzy Snapdragon

#ece018
Notes

Fizzy Snapdragon (#ECE018) is a true yellow 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 (57°, 85%, 51%) 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 blue. 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.

Snapdragon
noun

The genus Antirrhinum — particularly A. majus, the cottage-garden biennial whose tall flower spikes feature snapping dragon-mouth blooms in pinks, oranges, and yellows. The color refers to a yellow snapdragon bloom: a saturated, slightly red-shifted bright yellow with the matte finish of bee-pollinated flower stack.

WCAG contrast

The color used as foreground text against pure white and pure black, with the contrast ratio and WCAG 2.1 grade. Aim for AA (4.5:1) for body text and AA Large (3:1) for 18 pt+ headlines; AAA (7:1) is the gold standard for long-form reading surfaces.

Wide gamut

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.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
