Crushing Tudor

#66060a
Notes

Crushing Tudor (#66060A) 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 (358°, 89%, 21%) places it in the highly saturated band at a dark 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Crushing
adjective

Old French croissir, to crash / break — present-participle of crush. As a color modifier, crushing implies a deep-and-overwhelming-and-weighty quality where the hue exerts maximum visual force. Sits at the deep-and-weighty end of the grid, parallel to pressing with destructive register.

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.
