Tough Deneb Forest

Old English tōh, firm / tenacious — sharing root with German zäh. As a color modifier, tough implies a saturated-and-resilient quality where the hue resists fading-and-modulation through its strong pigmentation. Sits at the bold-and-resilient end of the grid, parallel to rugged and hardy in usage.

Arabic dhanab-al-dajājah, tail-of-the-hen. As a color modifier, deneb implies a Cygnus-tail-and-summer-triangle quality, the visual register of Cygnus-Swan-and-Summer-Triangle-Deneb hand-Cygnus-tail-and-summer-triangle Cygnus-Swan-and-Summer-Triangle-and-Bortle-1-sky deneb-and-Cygnus-tail-and-summer-triangle surfaces under Cygnus-Swan-and-Summer-Triangle-and-Bortle-1-sky July-and-August-summer-vista white-supergiant-stellar-light. Sits at the modifier-and-cosmic end of the grid, parallel to vega and altair 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.
