Plentiful Suo

#a91c7d
Notes

Plentiful Suo (#A91C7D) is a true magenta with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (319°, 72%, 39%) 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

Plentiful
adjective

Old French plentif, abundant — adjectival suffix -ful, derived from Latin plēnitās (fullness). As a color modifier, plentiful implies a saturated-and-generous quality where the hue carries rich visual abundance without restraint. Sits at the bold-and-saturated end of the grid, parallel to abundant and bountiful.

Suo
noun

Japanese 蘇芳, sappan-wood dye (Caesalpinia sappan) — derived from a Southeast Asian tree's heartwood, imported to Japan since the Nara period (710–794) for dyeing court robes a deep red-purple. Suo color refers to a suo-dyed Heian-period silk kinu: a saturated, slightly cool deep magenta with the silk luster of multi-bath sappan-wood dye on tussah silk. Distinct from akane (madder) and beni (safflower).
