Sturdy Eros Crimson

#e33323
Notes

Sturdy Eros Crimson (#E33323) 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 (5°, 77%, 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Sturdy
adjective

Old French estourdi, stunned, reckless — drifted in English to mean robust, well-built. Used as a color modifier since the seventeenth century for hues that read as durable and unfussy — the working browns of saddle leather, the working greens of pasture wool. Sits in the bold-and-warm corner alongside robust and solid.

Eros
modifier

Greek Ἔρως, god-of-love-and-desire. As a color modifier, eros implies a winged-love-and-arrow-of-desire quality, the visual register of Praxiteles-Eros-and-Roman-Cupid hand-winged-love-and-arrow-of-desire Praxiteles-Eros-and-Roman-Cupid-and-Pompeii-fresco eros-and-winged-love-and-arrow-of-desire surfaces under Praxiteles-Eros-and-Roman-Cupid-and-Pompeii-fresco Hellenistic-and-Roman-Pompeii rose-and-myrtle-light. Sits at the modifier-and-myth end of the grid, parallel to zeus and hera 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.
