Buttressed Wend Ruby

#a42d27
Notes

Buttressed Wend Ruby (#A42D27) is a true red with a warm character. It leans warm, pulling light toward red, orange, and yellow. Naturally inviting, it suits editorial and hospitality contexts. Its HSL profile (3°, 62%, 40%) 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

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.

Wend
modifier

Old English wendan, to-turn-or-go. As a color modifier, wend implies a winding-and-turning-and-meandered quality, the visual register of pilgrim-path-and-river-wend hand-winding-and-turning-and-meandered pilgrim-path-and-river-and-Roman-road wended-and-winding-and-turning-and-meandered surfaces under pilgrim-path-and-river-and-Roman-road Camino-and-Pennine-Way-and-Kumano hilltop-pilgrim-light. Sits at the modifier-and-mood end of the grid, parallel to drift and roam 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.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
