Heroic Nineveh

#a63ad1
Notes

Heroic Nineveh (#A63AD1) is a true violet 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 (283°, 62%, 52%) 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

Heroic
adjective

Latin hēroicus, of a hero — derived from Greek hērōs. As a color modifier, heroic implies a saturated-and-monumental-and-victorious quality, the deep-rich color of Wagner-and-Sibelius late-Romantic-era musical-and-painterly heroic-mode. Sits at the bold-and-celebratory end of the grid, parallel to triumphant and valiant.

Nineveh
noun

Assyrian capital (modern Mosul, Iraq) — the imperial court of Sennacherib (705–681 BCE), where Tyrian purple tribute textiles were imported from the Phoenician coast. Nineveh color refers to an Assyrian-court purpura-bordered tribute textile in the Library of Ashurbanipal: a saturated, slightly cool deep violet with the matte finish of multi-bath shellfish dye on hand-loomed Mesopotamian wool.

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.
