Funereal Yosemite

#0a367b
Notes

Funereal Yosemite (#0A367B) is a deep azure 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 (217°, 85%, 26%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Funereal
adjective

Latin fūnerālis, of the funeral — adjectival form of fūnus (funeral procession). As a color modifier, funereal implies the deep-mourning-and-formal darkness of Victorian-mourning black-textile and requiem-mass deep-violet vestment of Western Christian liturgical tradition. Sits at the deep-and-formal end of the grid, parallel to sepulchral and mourning in usage.

Yosemite
noun

The California national park in the Sierra Nevada — and the saturated deep blue of Half Dome's eastern shadow at sunset and the Yosemite Valley sky framed by El Capitan. Yosemite refers to the Yosemite Valley sky at sunset: a saturated, slightly cool deep blue with the optical depth of high-altitude desert sky.

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.
