Buttressed Lent Ruby

#ca204c
Notes

Buttressed Lent Ruby (#CA204C) 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 (344°, 73%, 46%) 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 teal. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Buttressed
adjective

Old French bouterez, thrusting-mass — past-participle of buttress, derived from bouter (to thrust). As a color modifier, buttressed implies a saturated-and-architecturally-supported quality, the deep-rich color of Gothic-Cathedral flying-buttress-and-rib-vault stone-architecture. Sits at the bold-and-fortified end of the grid, parallel to fortified and reinforced.

Lent
modifier

Latin Lententide, Lent / spring. As a color modifier, lent implies a Lenten-and-fasting-and-purple quality, the visual register of Roman-Catholic-and-Anglican Lenten-period purple-vestment-and-fast-and-ash-Wednesday liturgical surfaces under Lenten-purple ecclesiastical-vestment candlelight. Sits at the modifier-and-time end of the grid, parallel to advent and easter 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.
