Forceful Ametrine

#cb45d9
Notes

Forceful Ametrine (#CB45D9) is a true violet with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (294°, 66%, 56%) 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

Forceful
adjective

Old French force, strength — adjectival suffix -ful. As a color modifier, forceful implies a saturated-and-vigorous quality where the hue exerts visual force on its substrate. Sits at the bold-and-saturated end of the grid, parallel to mighty and commanding in tone.

Ametrine
noun

Naturally bicolored amethyst-citrine zoned quartz mined principally at the Anahí mine in eastern Bolivia. The deep-violet amethyst portion contrasts with the golden citrine zone in a single crystal. Ametrine color refers to the deep-violet amethyst zone of a polished Anahí-mine ametrine cabochon: a saturated, slightly cool deep violet with the glassy finish of iron-and-aluminum-substituted quartz under reflected light.

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.
