Lavish Night Ruby

#a31e24
Notes

Lavish Night Ruby (#A31E24) 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 (357°, 69%, 38%) 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

Lavish
adjective

Old French lavasse, downpour — sharing root with laver (to wash). As a color modifier, lavish implies a saturated-and-extravagant quality where the hue spills over its visual boundaries with luxurious pigmentation. Sits at the bold-and-saturated end of the grid, parallel to opulent and sumptuous in usage.

Night
modifier

Old English niht, darkness-and-sleep. As a color modifier, night implies a moonlit-or-star-lit-dark quality, the visual register of clear-sky moonlit-and-star-lit atmospheric Rayleigh-scattered low-light surfaces against deep blue-black night-sky horizon. Sits at the modifier-and-time end of the grid, parallel to eve and yore 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.
