Manorial Scarlet

#900b30
Notes

Manorial Scarlet (#900B30) 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 (343°, 86%, 30%) 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 teal. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Manorial
adjective

Latin manōrium, dwelling — adjectival suffix -al, derived from manēre (to remain). As a color modifier, manorial implies a saturated-and-aristocratic-and-rural quality, the deep-rich color of pre-modern English manor-house livery-and-tapestry tradition. Sits at the bold-and-aristocratic end of the grid, parallel to lordly and patrician.

Scarlet
noun

From the medieval Latin scarlatum, originally a fine wool cloth rather than a color — the dye came later when the fabric was associated with the bright red of kermes-stained textiles. The defining red of British military uniforms, fox-hunt coats, and The Scarlet Letter. Hotter than crimson, less orange than vermillion: a pure, attention-demanding red.

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.
