Voluptuous Surkh

#af3520
Notes

Voluptuous Surkh (#AF3520) is a true red with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (9°, 69%, 41%) 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 cyan. 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.

Surkh
noun

The Persian word for red in its most saturated, formal sense — used in Iranian poetry and miniature painting for the ribbons of court banners, the robes of warriors, and the high-saturation reds of Safavid tile. The color refers to a surkh-dyed Persian carpet: a saturated, slightly cool deep red with the matte finish of plant-dye-on-wool. Deeper than crimson, warmer than burgundy.

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.
