Earnest Rhodonite

#a90189
Notes

Earnest Rhodonite (#A90189) 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 (311°, 99%, 33%) 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

Earnest
adjective

Old English eornost, seriousness, zeal. Used as a color modifier since the nineteenth century for hues that read as committed but unshowy — the working blues of denim, the deep greens of Quaker meetinghouses. Sits in the bold-and-quiet corner of the grid, slightly less luminous than resolute and slightly less institutional than imperial.

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.

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
