Imperial Wane Forest

From the Latin imperialis, of the empire — applied to color since the medieval period for the hues reserved for sovereigns and empires: imperial purple of Tyrian dye, imperial yellow of Ming-dynasty porcelain. As a modifier, imperial implies saturation combined with the institutional weight of a color owned by a court. Sits in the bold-and-deep corner, alongside royal.

Old English wanian, to lessen. As a color modifier, wane implies a waning-moon-and-fading quality, the visual register of waning-moon-and-late-summer gradually-diminishing-and-receding waning-and-fading celestial-body-and-seasonal-light surfaces under waning-and-receding lunar-and-seasonal light. Sits at the modifier-and-time end of the grid, parallel to phase and eld 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.
