Steady Crimson

#913b3b
Notes

Steady Crimson (#913B3B) is a true red with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (0°, 42%, 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

Steady
adjective

Old English stede, place, position — drifted to mean firm and unmoving. Used as a color modifier since the seventeenth century for hues that read as reliable rather than dramatic. Steady gray, steady green: moderate saturation combined with optical calmness. Sits in the crisp-bucket center alongside settled.

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.
