Composed Tudor

#ac052b
Notes

Composed Tudor (#AC052B) 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°, 94%, 35%) 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

Composed
adjective

The past participle of compose, to arrange together — used as a color modifier for hues that read as deliberate and balanced. Composed black, composed gray: the saturation is moderate, the hue is calmly positioned without aggression. Sits at the bold-and-quiet edge of the grid near settled and resolute.

Tudor
noun

The English royal dynasty (1485–1603) — and the deep red of the Tudor Rose, the dynasty's symbol unifying the white rose of York and the red rose of Lancaster. Tudor red refers to the velvet of Henry VIII's portrait robes: a saturated, slightly cool deep red with the velvet's signature optical depth. Deeper than crimson, warmer than burgundy.
