Plumb Akamurasaki

#b56e99
Notes

Plumb Akamurasaki (#B56E99) 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 (324°, 32%, 57%) 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

Plumb
adjective

Latin plumbum, lead — referring to the lead-weighted plumb-line of pre-modern carpentry. As a color modifier, plumb implies a clear-and-vertical-true quality where the hue carries the visual register of gravity-aligned-and-perfectly-vertical surface. Sits at the crisp-and-balanced end of the grid, parallel to level and squared in usage.

Akamurasaki
noun

Japanese 赤紫, red-purple — the modern Japanese color name for the warm magenta-purple band that sits between aka (red) and murasaki (purple). Akamurasaki color refers to a Showa-period silk furisode obi: a saturated, slightly cool deep magenta with the silk luster of multi-bath beni-and-shikon overdye on patterned silk crepe. Slightly cooler than akane-iro.

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.
