Plentiful Frock Crimson

#c22929
Notes

Plentiful Frock Crimson (#C22929) 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 (0°, 65%, 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

Plentiful
adjective

Old French plentif, abundant — adjectival suffix -ful, derived from Latin plēnitās (fullness). As a color modifier, plentiful implies a saturated-and-generous quality where the hue carries rich visual abundance without restraint. Sits at the bold-and-saturated end of the grid, parallel to abundant and bountiful.

Frock
modifier

Old French froc, monk's-habit-or-loose-garment. As a color modifier, frock implies a monk's-habit-and-pinafore-and-day-frock quality, the visual register of Benedictine-monk's-frock-and-Edwardian-day-frock hand-monk's-habit-and-pinafore-and-day-frock Benedictine-monk's-frock-and-Edwardian-day-frock-and-pinafore frock-and-monk's-habit-and-pinafore surfaces under Benedictine-monk's-frock-and-Edwardian-day-frock-and-pinafore Cluny-Abbey-and-Edwardian-tea-room habit-and-day-dress-light. Sits at the modifier-and-textile end of the grid, parallel to gown and cope 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.
