Sturdy Magnus Crimson

#a92a21
Notes

Sturdy Magnus Crimson (#A92A21) 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°, 67%, 40%) 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.

Magnus
modifier

Latin magnus, great-or-large. As a color modifier, magnus implies a Latin-great-and-Albertus-Magnus-and-Magna-Carta quality, the visual register of Albertus-Magnus-and-Magna-Carta-magnus hand-Latin-great-and-Albertus-Magnus-and-Magna-Carta Albertus-Magnus-and-Magna-Carta-and-Charlemagne-Carolus-Magnus magnus-and-Latin-great surfaces under Albertus-Magnus-and-Magna-Carta-and-Charlemagne-Carolus-Magnus Cologne-cathedral-and-Runnymede-meadow medieval-Latin-light. Sits at the modifier-and-Latin end of the grid, parallel to opus and virtus 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.
