Tough Punch

#9c367b
Notes

Tough Punch (#9C367B) is a true magenta with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (319°, 49%, 41%) 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

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.

Punch
noun

A bright pink-red color named for the surface of a fruit punch — particularly the Tahitian-style punches of mid-century cocktail culture and the brand-name Hawaiian Punch whose color was a signature. The color refers to a saturated, slightly cool red-pink: brighter than fuchsia, warmer than rose, with the mid-century-tropical weight of a color tied to a specific decade of American cookout entertaining.
