Buttressed Momoiro

#a61d90
Notes

Buttressed Momoiro (#A61D90) is a true magenta 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 (310°, 70%, 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 green. 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.

Momoiro
noun

Japanese 桃色, peach color — though traditionally referring to the warm pink of Prunus persica peach blossom, the modern color name momoiro extends to the deep-saturated magenta-pink of cultivated double-petaled peach varieties. Momoiro color refers to a fully bloomed Prunus persica var. plena double-flower: a saturated, slightly cool deep magenta with the velvet finish of densely overlapping ruffled peach-blossom petals.
