Latin certus, fixed / sure — sharing root with English concern and certify. As a color modifier, certain implies a saturated-and-unambiguous quality where the hue declares its character without hesitation. Sits at the bold-and-confident end of the grid, parallel to assured and decisive in usage.

Old French buffer, to-puff. As a color modifier, buffed implies a polished-and-shined quality, the visual register of Sheffield-and-Renaissance-buffed-and-polished hand-buffed-and-polished metal-and-leather-and-wood Sheffield-and-Renaissance-buffed-and-polished surfaces under Sheffield-and-Renaissance hand-buffed-and-polished workshop-light.

The genus Morus — the white mulberry (M. alba) feeds silkworms; the black mulberry (M. nigra) bears the deep purple fruit that stains everything it touches. The color refers to a ripe black mulberry: a saturated, slightly red-shifted very deep purple with the slight juiciness of a compound fruit. Cooler than wine, warmer than indigo, with the agricultural weight of a tree that supported the entire Chinese silk industry for two thousand years.
