Forthright Helio

#9b24b5
Notes

Forthright Helio (#9B24B5) 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 (289°, 67%, 43%) 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.

Helio
noun

A shortened form of heliotrope — sometimes used as a slightly more genteel color name in late-Victorian fashion catalogues, particularly for the pale lavender-purple silks of mourning dress's transition out of full black. The color refers to a Victorian Helio silk: a soft, slightly muted pale purple with the satiny finish of a fabric dyed to register a specific point in the mourning calendar. Lighter than mauve, cooler than lilac.

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.
