Wellbred Plot Crimson

#e3042b
Notes

Wellbred Plot Crimson (#E3042B) 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 (350°, 97%, 45%) 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 teal. 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.

Plot
modifier

Old English plot, small-piece-of-ground. As a color modifier, plot implies a tilled-garden-bed quality, the visual register of English-cottage-garden-and-allotment hand-tilled-and-cultivated small market-garden vegetable-bed surfaces under English-cottage-garden-and-allotment summer-tilling light. Sits at the modifier-and-place end of the grid, parallel to yard and garden in usage.

Crimson
noun

From the Old Spanish cremesin, itself from the Arabic qirmiz — the kermes scale insect, dried and ground into a brilliant carmine dye prized in the medieval Mediterranean. For centuries the most expensive red on a draper's shelf, reserved for cardinals, kings, and the cloth that gave English the word crimson. Cooler than scarlet, deeper than rose; the color of pomegranate seeds and a serious occasion.

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.
