Dark Toga

#421054
Notes

Dark Toga (#421054) 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 (284°, 68%, 20%) 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

Dark
adjective

Old English deorc, dark, gloomy — cognate with the German dunkel and the Latin terra, earth, both pointing to a base meaning of covered or obscured. As a color modifier, dark sits on the lightness axis only: it says nothing about hue or saturation, only that the value is low. Used across every adjective bucket the engine routes to when L < 0.40.

Toga
noun

The Roman ceremonial-citizen mantle — particularly the toga picta (painted toga) worn by triumphant generals and emperors, dyed entirely in Tyrian purple with gold-thread embroidered figures. Toga color refers to a Roman-imperial toga picta on a triumphal arch spolia relief: a saturated, slightly cool deep violet with the matte finish of multi-bath Tyrian shellfish-dye on multi-rolled woolen toga cloth. Distinct from the white toga virilis.

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.
