Forthright Yosemite

#3763b5
Notes

Forthright Yosemite (#3763B5) is a true azure with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (219°, 53%, 46%) 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

Forthright
adjective

Old English forð-riht, straight ahead, direct. Used as a color modifier in Anglo-Saxon-revival contexts for hues that read as honest and unguarded. Forthright red, forthright blue: the saturation is full, the hue is presented without ornamentation or qualification. Sits in the bold-bucket center alongside frank and direct.

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.
