Hefty Gown Ruby

#991c18
Notes

Hefty Gown Ruby (#991C18) is a true red 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 (2°, 73%, 35%) 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

Hefty
adjective

Old English hefig, heavy — adjectival suffix -y. As a color modifier, hefty implies a saturated-and-substantial-and-weighty quality where the hue carries the visual heft of a hand-cast pig-iron object. Sits at the bold-and-weighty end of the grid, parallel to substantial and weighty in usage.

Gown
modifier

Old French goune, long-loose-garment. As a color modifier, gown implies a Tudor-and-Elizabethan-and-formal-evening-gown quality, the visual register of Tudor-and-Elizabethan-and-Worth-couture-gown hand-Tudor-and-Elizabethan-and-formal-evening-gown Tudor-and-Elizabethan-and-Worth-couture-gown-and-Belle-Époque gown-and-Tudor-and-Elizabethan surfaces under Tudor-and-Elizabethan-and-Worth-couture-gown-and-Belle-Époque Hampton-Court-and-Maison-Worth-Paris court-and-couture-light. Sits at the modifier-and-textile end of the grid, parallel to robe and frock 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.
