Tough Shawl Crimson

#ad2d23
Notes

Tough Shawl Crimson (#AD2D23) 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 (4°, 66%, 41%) 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

Tough
adjective

Shawl
modifier

Persian shāl, long-folded-wrap. As a color modifier, shawl implies a Persian-Kashmiri-and-paisley-folded-wrap quality, the visual register of Persian-Kashmiri-and-paisley-shawl hand-Persian-Kashmiri-and-paisley-folded-wrap Persian-Kashmiri-and-paisley-shawl-and-Norwich-and-Paisley-loom shawl-and-Persian-Kashmiri-and-paisley-folded-wrap surfaces under Persian-Kashmiri-and-paisley-shawl-and-Norwich-and-Paisley-loom Mughal-Kashmir-and-Norwich-and-Paisley-loom paisley-shawl-light.

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.
