Voluptuous Konjō

#1c8fd4
Notes

Voluptuous Konjō (#1C8FD4) 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 (203°, 77%, 47%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Voluptuous
adjective

Latin voluptuōsus, pleasurable — derived from voluptās (pleasure). As a color modifier, voluptuous implies a saturated-and-rich-and-curving-sensual quality, the deep-rich color of Rubens-and-Boucher baroque-and-rococo flesh-and-fabric tonality. Sits at the bold-and-saturated end of the grid, parallel to lush and plush in tone.

Konjō
noun

Japanese konjō (紺青) — deep blue-azure, the saturated deep navy used in Edo-period samurai inner robes and Buddhist mandala backgrounds. Distinct from konpeki by its slightly cooler shift toward navy. The color refers to a konjō-dyed silk: a saturated, slightly cool dark blue with the satin finish of multi-bath dyed silk.

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.
