True Court Cardinal

#83291a
Notes

True Court Cardinal (#83291A) is a deep 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 (9°, 67%, 31%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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

True
adjective

Old English trēowe, faithful — used as a color modifier since the seventeenth century for hues that read as the canonical version of their family. True red, true blue: the saturation is full, the hue is neither shifted nor adulterated. Sits at the center of the bold and crisp buckets, marking the unequivocal middle of any chromatic family.

Court
modifier

Old French cort, enclosed-yard. As a color modifier, court implies an enclosed-courtyard quality, the visual register of Inn-of-Court-and-Chinese-courtyard hand-built stone-and-tile-paved enclosed-and-formal courtyard-architecture surfaces under London-Inn-of-Court-and-Chinese-courtyard enclosed-formal architecture light. Sits at the modifier-and-place end of the grid, parallel to quad and yard in usage.

Cardinal
noun

Named for the scarlet robes of Roman Catholic cardinals, dyed since the thirteenth century with kermes and later cochineal. The color carries the institutional weight of its source — a saturated red-orange that reads as authority rather than romance. Also the bird (Cardinalis cardinalis) of the American east, whose plumage takes its red from carotenoid pigments in the seeds it eats.

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.
