Tough Rhodolite

#b01133
Notes

Tough Rhodolite (#B01133) is a true red 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 (347°, 82%, 38%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary teal. 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.

Rhodolite
noun

A pyrope-almandine garnet hybrid — the rose-pink-red gem mined principally in Tanzania and Mozambique, named for the Greek rhodon (rose) for its distinctive raspberry-pink saturation. The color refers to a faceted rhodolite: a saturated, slightly cool red-pink with the gem's signature internal life. Cooler than pyrope, lighter than ruby.
