Etymology

Cultured
adjective

Latin cultūra, cultivation — past-participle of culture. As a color modifier, cultured implies a neutral-and-cultivated-and-educated quality, the neutral color of Edwardian-and-Belle-Époque cultivated-and-educated-and-refined elegant-and-cultivated interior-decoration-and-dress-attire coordinated-color tone. Sits at the neutral-and-cultivated end of the grid, parallel to refined and polished in usage.

Stratocumulus
noun

Latin stratus (layer) and cumulus (heap) — the iconic pale-cool-pale-gray low-altitude stratocumulus cloud-form, the most common cloud over the world's oceans. Stratocumulus color refers to a stratocumulus cloud-deck over the Bay-of-Biscay in November-overcast: a pale cool gray with the optical complexity of low-altitude water-droplet scattering against November overcast Atlantic-coast sky.
