Triumphant Helio

#7f2aad
Notes

Triumphant Helio (#7F2AAD) is a true indigo with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (279°, 61%, 42%) 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Triumphant
adjective

Latin triumphāns, celebrating victory — present-participle of triumphāre. As a color modifier, triumphant implies a saturated-and-celebratory-and-victorious quality, the deep-rich color of Roman-Imperial-period triumphal-arch spolia relief and Arch-of-Titus victory imagery. Sits at the bold-and-celebratory end of the grid, parallel to victorious and conquering.

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.

Wide gamut

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.
