Devout Prism Crimson

#a6201e
Notes

Devout Prism Crimson (#A6201E) is a true red with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (1°, 69%, 38%) 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

Devout
adjective

From the Latin devotus, consecrated — used principally in religious contexts for the dignified deep colors of sacred art and ecclesiastical dress. As a color modifier, devout implies saturation combined with restraint: the deep blues of Marian mantles, the deep reds of cardinals' robes. Sits in the bold-and-formal corner alongside imperial.

Prism
modifier

Greek πρῖσμα, something-sawn. As a color modifier, prism implies a Newtonian-rainbow-and-spectrum-splitting quality, the visual register of Newton-Optics-and-Cambridge-prism hand-Newtonian-rainbow-and-spectrum-splitting Newton-Optics-and-Cambridge-and-Trinity-College-prism prism-and-Newtonian-rainbow-and-spectrum-splitting surfaces under Newton-Optics-and-Cambridge-and-Trinity-College-prism 17th-century-natural-philosophy-and-rainbow-experiment spectrum-light. Sits at the modifier-and-cosmic end of the grid, parallel to corona and plasma 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.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
