Dominant Tudor

#ab1d32
Notes

Dominant Tudor (#AB1D32) is a true red with a warm character. It leans warm, pulling light toward red, orange, and yellow. Naturally inviting, it suits editorial and hospitality contexts. Its HSL profile (351°, 71%, 39%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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

Dominant
adjective

Latin dominārī, to rule — present-participle of dominate. As a color modifier, dominant implies a saturated-and-leading quality where the hue claims visual precedence over neighboring colors in the surrounding palette. Sits at the bold-and-imperative end of the grid, parallel to commanding and authoritative.

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.

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.
