Opulent Savory Sapphire

#243cab
Notes

Opulent Savory Sapphire (#243CAB) is a true blue with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (229°, 65%, 41%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Opulent
adjective

Latin opulentus, rich / wealthy — derived from ops (wealth). As a color modifier, opulent implies a saturated-and-luxurious quality, the deep-rich color of Belle-Époque and Gilded-Age interior-decoration silk-and-velvet textiles. Sits at the bold-and-saturated end of the grid, parallel to lavish and sumptuous.

Savory
modifier

Latin satureia, peppery-Mediterranean-herb. As a color modifier, savory implies a peppery-Mediterranean-herb-and-Provençal-bouquet quality, the visual register of Provençal-bouquet-garni-and-summer-savory hand-peppery-Mediterranean-herb-and-Provençal-bouquet Provençal-bouquet-garni-and-summer-savory-and-herbes-de-Provence savory-and-peppery-Mediterranean-herb surfaces under Provençal-bouquet-garni-and-summer-savory-and-herbes-de-Provence Provençal-and-Tuscan-and-Catalan herb-garden-light. Sits at the modifier-and-flavor end of the grid, parallel to hyssop and lovage 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.
