Robust Moot Crimson

#da063a
Notes

Robust Moot Crimson (#DA063A) is a true red with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (345°, 95%, 44%) 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

Robust
adjective

From the Latin robustus, of oak — implying strength combined with substance. As a color modifier, robust describes saturation combined with body: a robust burgundy, a robust olive. Sits in the bold-and-warm corner alongside strong and solid, with the slightly textural implication of a color that has substance behind the pigment.

Moot
modifier

Old English mōt, meeting-or-debate-point. As a color modifier, moot implies a debated-and-suspended-and-undecided quality, the visual register of Anglo-Saxon-witenagemot-and-Inns-of-Court-moot hand-argued-and-suspended Anglo-Saxon-witenagemot-and-medieval-moot-court witenagemot-and-Inns-of-Court-and-shire-court mooted-and-debated surfaces under Anglo-Saxon-witenagemot-and-Inns-of-Court oak-bench-and-vellum debate-hall-light. Sits at the modifier-and-mood end of the grid, parallel to void and blank 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.

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.
