Sumptuous Sand

#c1780a
Notes

Sumptuous Sand (#C1780A) is a true amber with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (36°, 90%, 40%) 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 azure. 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.

Sand
noun

Quartz weathered to grain — the residue of geologic time at the granular scale. Beach sand color depends entirely on the source: white from Caribbean coral, black from Hawaiian basalt, red from Australian iron oxide. The reference shade is the warm, slightly golden tan of a temperate Atlantic beach: medium-saturation, matte, with the optical brightness of small mineral particles in sunlight.

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.
