Tough Murasakiawa

#81178b
Notes

Tough Murasakiawa (#81178B) 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 (295°, 72%, 32%) 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

Tough
adjective

Old English tōh, firm / tenacious — sharing root with German zäh. As a color modifier, tough implies a saturated-and-resilient quality where the hue resists fading-and-modulation through its strong pigmentation. Sits at the bold-and-resilient end of the grid, parallel to rugged and hardy in usage.

Murasakiawa
noun

Japanese pale-purple shade (薄紫, usu-murasaki in modern usage) — historically a kasane layer color combining a thin gromwell-dyed silk over a pale silk substrate. Murasakiawa color refers to a Heian-period second-rank kasane sleeve layer: a saturated, slightly cool deep violet with the silk luster of single-bath gromwell-root dye on layered silk crepe. Slightly cooler than full murasaki.

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.
