Rich Nova Forest

Old French riche, wealthy, abundant — applied to color since the medieval period for hues that read as plentiful in pigment. Rich red, rich brown: the implication is depth combined with saturation, a color that gives the eye more to absorb. Sits at the saturated mid-light corner of the engine's grid, slightly warmer than bold and deeper than vivid.

Latin nova, new-or-newly-bright-star. As a color modifier, nova implies a sudden-bright-and-newly-erupted-and-flaring quality, the visual register of Tycho-Brahe-and-Kepler-supernova-nova hand-sudden-bright-and-newly-erupted Tycho-Brahe-and-Kepler-and-Cassiopeia-A nova-and-sudden-bright-and-flaring surfaces under Tycho-Brahe-and-Kepler-and-Cassiopeia-A late-Renaissance-observatory-and-naked-eye sudden-stellar-light. Sits at the modifier-and-cosmic end of the grid, parallel to flare and spark 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.
