Voluptuous Forged Ruby

#d52d26
Notes

Voluptuous Forged Ruby (#D52D26) 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 (2°, 70%, 49%) 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.

Forged
modifier

Old French forgier, to-forge. As a color modifier, forged implies a hand-hammered-iron quality, the visual register of blacksmith-and-armorer-forged hand-hammered-and-tempered iron-and-steel-and-bronze blacksmith-and-armorer-forged surfaces under blacksmith-and-armorer-forge bellows-and-anvil light. Sits at the modifier-and-texture end of the grid, parallel to hewn and cast in usage.

Ruby
noun

From the Latin ruber — simply, red. The gemstone is a chromium-tinged corundum, harder than anything in nature except diamond, and so saturated that a fine Burmese pigeon's blood ruby at auction outpaces a comparable diamond by weight. The color borrows the gem's confidence: a clear, glassy red without the brown of garnet or the blue of crimson.

Wide gamut

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
