Buttressed Mira Ruby

#d3234d
Notes

Buttressed Mira Ruby (#D3234D) 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 (346°, 72%, 48%) 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.

Mira
modifier

Latin mira, wonderful-or-marvelous. As a color modifier, mira implies a variable-pulsing-and-red-giant-and-wondrous quality, the visual register of Cetus-Whale-and-variable-Mira-the-Wonder hand-variable-pulsing-and-red-giant-and-wondrous Cetus-Whale-and-variable-Mira-and-Hevelius-discovery mira-and-variable-pulsing-and-red-giant-and-wondrous surfaces under Cetus-Whale-and-variable-Mira-and-Hevelius-discovery 332-day-cycle-and-deep-red-pulse pulsing-stellar-light. Sits at the modifier-and-cosmic end of the grid, parallel to nova and pulsar 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.
