Buttressed Blithe Ruby

#d72151
Notes

Buttressed Blithe Ruby (#D72151) 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%, 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 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.

Blithe
modifier

Old English blīthe, joyful-and-kind. As a color modifier, blithe implies a carefree-and-light-hearted-and-cheerful quality, the visual register of Shakespearean-pastoral-and-Forest-of-Arden-blithe hand-carefree-and-light-hearted-and-cheerful Shakespearean-pastoral-and-Forest-of-Arden-and-As-You-Like-It blithe-and-carefree-and-light-hearted-and-cheerful surfaces under Shakespearean-pastoral-and-Forest-of-Arden-and-As-You-Like-It English-greenwood-and-shepherd's-meadow Maytime-light. Sits at the modifier-and-mood end of the grid, parallel to merry and jolly 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.
