Forthright Eudialyte

#a6187f
Notes

Forthright Eudialyte (#A6187F) is a true 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 (316°, 75%, 37%) 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

Forthright
adjective

Old English forð-riht, straight ahead, direct. Used as a color modifier in Anglo-Saxon-revival contexts for hues that read as honest and unguarded. Forthright red, forthright blue: the saturation is full, the hue is presented without ornamentation or qualification. Sits in the bold-bucket center alongside frank and direct.

Eudialyte
noun

Rare zirconium-cyclosilicate first described from Greenland's Ilímaussaq Complex in 1819. The mineral's deep-raspberry-pink color comes from manganese substitution in the cyclosilicate ring sites. Eudialyte color refers to a polished Ilímaussaq eudialyte cabochon: a saturated, slightly cool deep magenta with the glassy finish of complex zirconium-sodium-cyclosilicate. The Greek genus name eu-dialytos means easily decomposed in acid.

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.
