Submerged Frangipani

#670c5b
Notes

Submerged Frangipani (#670C5B) is a deep violet 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 (308°, 79%, 23%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Submerged
adjective

Latin sub-mergere, to plunge under — past-participle of submerge. As a color modifier, submerged implies the cool, deep, slightly-shifted quality of a hue viewed through a layer of water or glass. Sits at the deep-and-cool end of the grid, parallel to drowned and sunken 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.
