Sturdy Limed Crimson

#b5242d
Notes

Sturdy Limed Crimson (#B5242D) 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 (356°, 67%, 43%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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.

Limed
modifier

Old English līm, lime. As a color modifier, limed implies a lime-washed-and-whitened quality, the visual register of Andalusian-and-Mediterranean-limewashed hand-limed-and-whitewashed stone-and-stucco-and-timber Andalusian-and-Mediterranean-limewashed surfaces under Andalusian-and-Mediterranean lime-washed-and-whitened light. Sits at the modifier-and-texture end of the grid, parallel to mossed and pitted 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.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
