Sonorous Cranberry

#a31f40
Notes

Sonorous Cranberry (#A31F40) 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 (345°, 68%, 38%) 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 teal. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Sonorous
adjective

Latin sonōrus, resounding — derived from sonus (sound). As a color modifier, sonorous implies a saturated-and-richly-vibrating quality where the hue carries the deep-resonance visual register of a cathedral-organ-pipe low-note. Sits at the bold-and-resonant end of the grid, parallel to resonant and deep 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.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
