Wellbred Annatto

#f30d15
Notes

Wellbred Annatto (#F30D15) is a true red 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 (358°, 91%, 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Wellbred
adjective

Old English wel-brēd, well-bred — past-participle of breed, sharing root with brood (offspring). As a color modifier, wellbred implies a saturated-and-elegant-and-formal quality, the deep-rich color of Edwardian-period finishing-school-and-debutante-Court English-aristocratic livery. Sits at the bold-and-elegant end of the grid, parallel to highborn and patrician.

Annatto
noun

Bixa orellana, the tropical shrub whose seeds yield a red-orange dye used as food coloring (in cheese, butter, and margarine) and as body paint by the Caribbean and Central American indigenous peoples. The color refers to fresh annatto paste: a saturated, slightly orange red with the matte finish of plant-derived pigment. Warmer than vermillion, drier than tomato.

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.
