Sumptuous Sintra

#4287e6
Notes

Sumptuous Sintra (#4287E6) 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 (215°, 77%, 58%) 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.

Sintra
noun

The Portuguese palace town northwest of Lisbon — and the saturated blue of Pena Palace's Manueline tile facades and the deep Atlantic blue of the surrounding Serra de Sintra. The color refers to Pena Palace's blue-tile pavilion: a saturated, slightly cool deep blue with the high gloss of azulejo tile.
