Heavy Aisle Aubergine

#400e42
Notes

Heavy Aisle Aubergine (#400E42) is a deep violet 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 (298°, 65%, 16%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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

Heavy
adjective

Old English hefig, weighty — cognate with heave. Used as a color modifier since at least the seventeenth century to indicate weight in saturation as much as value: heavy with pigment, heavy-bodied. In the engine's adjective grid, heavy sits alongside deep and plush in the dark-and-saturated quadrant. Closer to a fabric description than a pure value word.

Aisle
modifier

Old French aisile, side-aisle. As a color modifier, aisle implies a side-aisle-flanking-nave quality, the visual register of Romanesque-and-Gothic-cathedral hand-built side-aisle-and-arcade column-and-arch flanking-the-nave architectural surfaces under Gothic-and-Romanesque side-aisle filtered light. Sits at the modifier-and-architecture end of the grid, parallel to nave and apse in usage.

Aubergine
noun

The French and British name for the eggplant — borrowed from the Catalan albergínia and ultimately from the Sanskrit vātiṅgaṇa. Aubergine as a color name carries with it the slightly more aristocratic register of the European-language version of the word. The color refers to the same fruit as eggplant but shifted slightly redder in popular usage: a saturated, slightly red-shifted very deep purple with the polished finish of waxy fruit. Cooler than wine, warmer than indigo.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
