Cavalier Lintel Crimson

#ad1424
Notes

Cavalier Lintel Crimson (#AD1424) 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 (354°, 79%, 38%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary teal. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Cavalier
adjective

Italian cavaliere, horseman / knight via Latin caballārius. As a color modifier, cavalier implies a saturated-and-chivalrous-and-aristocratic quality, the deep-rich color of English-Civil-War royalist Cavalier military-faction velvet-and-lace-and-feathered-hat livery. Sits at the bold-and-chivalrous end of the grid, parallel to gallant and knightly.

Lintel
modifier

Old English lyn-trigan, threshold-beam. As a color modifier, lintel implies a horizontal-load-bearing-beam-above-door quality, the visual register of Stonehenge-and-medieval-stone-lintel hand-cut horizontal-load-bearing stone-and-timber lintel-above-door architectural surfaces under medieval-stone-and-timber lintel-above-door light. Sits at the modifier-and-architecture end of the grid, parallel to sill and truss 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.
