Submersed Rhodonite

#300927
Notes

Submersed Rhodonite (#300927) is a deep 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 (314°, 68%, 11%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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

Submersed
adjective

Latin sub-mersus, plunged-under — past-participle of submerse. As a color modifier, submersed implies the deep-saturated-and-cool-shifted quality of a hue viewed through a layer of water, like an underwater coral-reef object seen from a glass-bottomed boat. Sits at the deep-and-cool end of the grid, parallel to submerged with slightly-archaic register.

Rhodonite
noun

Manganese-silicate mineral with deep-pink-to-rose-red coloration, sourced from the Sverdlovsk deposits of the Russian Urals and the Vagner mine of Sweden. Rhodonite color refers to a polished Sverdlovsk rhodonite massive specimen: a saturated, slightly cool deep magenta with the matte finish of manganese-rich silicate. The Greek genus name rhódon (rose) refers to the characteristic deep-pink color of crystalline specimens.
