Tough Pinotage

#90167b
Notes

Tough Pinotage (#90167B) is a deep magenta 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 (310°, 73%, 33%) 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.

Pinotage
noun

South African red-wine grape variety, a 1925 cross of Pinot Noir and Cinsaut by Stellenbosch University viticulturist Abraham Izak Perold. Pinotage color refers to a freshly poured South African Stellenbosch-region pinotage in a Bordeaux-style wine glass: a saturated, slightly cool deep magenta with the matte finish of anthocyanin-rich red-wine pigment. The grape's acetate-character gives it the banana-and-tar notes characteristic of South African reds.
