Glowy Bruciato

#ef5c21
Notes

Glowy Bruciato (#EF5C21) is a true orange 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 (17°, 87%, 53%) 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Glowy
adjective

Old English glōwan, to glow — adjectival suffix -y. As a color modifier, glowy implies a saturated-and-soft-emitting-and-warm quality, the bright color of fireside-and-candle-lit interior atmospheric-warmth surface emission. Sits at the bright-and-warm end of the grid, parallel to glowing and luminous in usage.

Bruciato
noun

The Italian word for burnt — used in pigment vocabulary for terra di Siena bruciata (burnt sienna) and terra d'ombra bruciata (burnt umber). Bruciato implies a color that has been concentrated by heat. The color refers to a Sienese bruciato-pigment: a warm, slightly muted deep orange-brown with the matte finish of fired iron-oxide pigment.

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.
