Drained Yosemite

#182a7b
Notes

Drained Yosemite (#182A7B) is a deep blue 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 (229°, 67%, 29%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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

Drained
adjective

Old English drēahnian, to filter — past-participle of drain. As a color modifier, drained implies a deep-and-emptied-and-pallid quality where the hue's vital warmth has been removed. Sits at the deep-and-cool end of the grid, parallel to deathly with desaturation overtone.

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.
