Smoldering Cupola Forest

The progressive participle of smolder, to burn slowly without flame. Used as a color word since the late nineteenth century for the deep reds and oranges of barely-flame coal — the warm saturated darks where the heat is internal rather than emitted. Sits in the bold-and-warm corner, slightly less luminous than burning and slightly less calm than rich.

Italian cupola, small-dome. As a color modifier, cupola implies a small-roof-dome quality, the visual register of Italian-and-American-Cupola hand-built small-rooftop dome-and-lantern decorative-cupola architectural surfaces under Italian-villa-and-American-courthouse cupola light. Sits at the modifier-and-architecture end of the grid, parallel to dome and turret in usage.

The dense canopy of a temperate or tropical woodland — oak, beech, pine, eucalyptus, mahogany — wherever leaves close above to filter the light below. Forest green refers to the average reflectance of a healthy mid-summer canopy seen from below: a saturated, slightly muted green with the matte finish of layered chlorophyll. Deeper than fern, cooler than olive, with the ecological weight of a word that has named every wooded biome on Earth.
