Sonorous Erdbeere

#a11c86
Notes

Sonorous Erdbeere (#A11C86) is a true 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 (312°, 70%, 37%) 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

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.

Erdbeere
noun

German for strawberry (Fragaria × ananassa) — particularly the deep-magenta Hanseatic harvest strawberry of Schleswig-Holstein and Niederrhein river-meadows, the iconic summer-fruit base of Erdbeerkuchen. Erdbeere color refers to a freshly hulled Fragaria × ananassa aggregate-fruit cross-section in a Hamburg market stall: a saturated, slightly cool deep magenta with the matte finish of anthocyanin-rich strawberry-flesh against pale yellow-green achenes.
