Sumptuous Brazilin

#870578
Notes

Sumptuous Brazilin (#870578) is a deep violet 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 (307°, 93%, 27%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Sumptuous
adjective

Latin sūmptuōsus, expensive — derived from sūmptus (expense). As a color modifier, sumptuous implies a saturated-and-rich-and-luxurious quality, the deep-rich color of Burgundy-and-Champagne-Court late-medieval silk-and-velvet livery in the Très-Riches-Heures manuscript tradition. Sits at the bold-and-saturated end of the grid, parallel to opulent and lavish.

Brazilin
noun

Caesalpinia brasiliensis — a Brazilian legume tree whose heartwood was the colonial-era principal source of brazilin dye, harvested at industrial scale from the Mata Atlântica and giving the country Brazil its English name. Brazilin color refers to a freshly brazilin-mordant-dyed wool: a saturated, slightly cool deep magenta with the matte finish of multi-bath plant-and-mordant-dyed woolen fiber. Warmer than campeche (logwood).

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
