Tough Quilt Cardinal

#bb0934
Notes

Tough Quilt Cardinal (#BB0934) 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 (346°, 91%, 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

Tough
adjective

Old English tōh, firm / tenacious — sharing root with German zäh. As a color modifier, tough implies a saturated-and-resilient quality where the hue resists fading-and-modulation through its strong pigmentation. Sits at the bold-and-resilient end of the grid, parallel to rugged and hardy in usage.

Quilt
modifier

Old French cuilte, padded-cushion. As a color modifier, quilt implies a hand-quilted-padded-textile quality, the visual register of American-and-English-quilt hand-quilted-and-padded patchwork-and-coverlet hand-quilted-and-padded textile surfaces under American-and-English hand-quilted-and-padded textile workshop-light. Sits at the modifier-and-texture end of the grid, parallel to tufted and flock 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.
