Sinewy Cranberry

#a00b37
Notes

Sinewy Cranberry (#A00B37) is a deep 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 (342°, 87%, 34%) places it in the highly saturated band at a dark 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

Sinewy
adjective

Old English sinu, sinew — adjectival suffix -y. As a color modifier, sinewy implies a saturated-and-muscular-and-firm quality where the hue carries the lean-and-strong visual presence of a Roman-statue athletic figure. Sits at the bold-and-firm end of the grid, parallel to stalwart and rugged in usage.

Cranberry
noun

North American Vaccinium macrocarpon — a Ericaceae low-creeping wetland shrub whose deep-magenta drupe is the iconic Thanksgiving fruit and the base of cranberry juice and jellied cranberry sauce. Cranberry color refers to a freshly cooked Vaccinium macrocarpon compote in a Massachusetts kitchen: a saturated, slightly cool deep magenta with the matte finish of anthocyanin-rich cranberry-fruit pulp.
