Sterile Frangipani

#aa6b9b
Notes

Sterile Frangipani (#AA6B9B) 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 (314°, 27%, 54%) places it in the muted 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

Sterile
adjective

Latin sterilis, barren / not-fertile — sharing root with Greek steiros (barren). As a color modifier, sterile implies a clear-and-medical-clean-and-stripped quality, the crisp color of operating-theater surgical-environment white-and-stainless-steel surfaces. Sits at the crisp-and-clean end of the grid, parallel to sanitary and hygienic in usage.

Frangipani
noun

Caribbean and Polynesian Plumeria rubra — a tropical Apocynaceae tree cultivated worldwide for its highly fragrant five-petaled flowers in deep-magenta cultivars. The flowers are used in Hawaiian lei and Hindu garlands. Frangipani color refers to a freshly opened Plumeria rubra deep-magenta flower: a saturated, slightly cool deep magenta with the velvet finish of overlapping fleshy five-petaled corolla. Named for the Italian noble family that invented the perfume.
