Sturdy Down Crimson

#c02b31
Notes

Sturdy Down Crimson (#C02B31) is a true red with a warm character. It leans warm, pulling light toward red, orange, and yellow. Naturally inviting, it suits editorial and hospitality contexts. Its HSL profile (358°, 63%, 46%) 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.

Down
modifier

Old Norse dúnn, down / soft-feather. As a color modifier, down implies a soft-feather-undercoat quality, the visual register of eider-and-goose-down hand-plucked-and-cleaned eider-and-goose-down soft-feather-undercoat surfaces under eider-and-goose-down hand-plucked-and-cleaned bedding-and-cushion light. Sits at the modifier-and-texture end of the grid, parallel to fluff and fur 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.
