Sumptuous Mossed Sapphire

#1951bf
Notes

Sumptuous Mossed Sapphire (#1951BF) is a true azure with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (220°, 77%, 42%) 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 amber. 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.

Mossed
modifier

Old English mos, moss. As a color modifier, mossed implies a moss-covered-and-aged quality, the visual register of English-and-Welsh-mossed-and-lichen-covered moss-and-lichen-covered stone-and-tree-and-cobble mossed-and-lichen-covered surfaces under English-and-Welsh moss-and-lichen-covered atmospheric light. Sits at the modifier-and-texture end of the grid, parallel to pitted and limed in usage.

Sapphire
noun

An iron-and-titanium-bearing corundum — the same mineral as ruby, hardness 9 on the Mohs scale, mined for two millennia from Sri Lanka, Burma, Madagascar, and the Cashmere mines of British India. The color refers to a fine Kashmir-cut sapphire: a saturated, slightly violet-shifted deep blue with the gem's signature internal velvet — a quality of light scattering in the stone that faceted glass cannot replicate. Cooler than cobalt, deeper than azure.
