Smoldering Gloam 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.

Old English glōm, twilight-or-dusk. As a color modifier, gloam implies a twilight-and-half-light-and-fading quality, the visual register of Scottish-Border-and-Hebridean-gloam hand-twilight-and-half-light-and-fading Scottish-Border-and-Hebridean-and-Orkney gloamed-and-twilight-and-fading surfaces under Scottish-Border-and-Hebridean-and-Orkney long-northern-twilight-and-blue-hour gloaming-and-twilight light. Sits at the modifier-and-mood end of the grid, parallel to dusk and shade 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.
