Chivalrous Rigel Forest

Old French chevaleros, knightly — adjectival suffix -ous, derived from cheval (horse). As a color modifier, chivalrous implies a saturated-and-knightly-and-gallant quality, the deep-rich color of medieval-Romance chanson-de-geste hero-and-troubadour song tradition. Sits at the bold-and-chivalrous end of the grid, parallel to gallant and knightly.

Arabic rijl-al-jawzā', foot-of-Orion. As a color modifier, rigel implies a blue-supergiant-and-Orion-foot quality, the visual register of Orion-Hunter-and-winter-blue-supergiant-Rigel hand-blue-supergiant-and-Orion-foot Orion-Hunter-and-winter-blue-supergiant-and-Bortle-1 rigel-and-blue-supergiant-and-winter-zenith surfaces under Orion-Hunter-and-winter-blue-supergiant-and-Bortle-1 January-and-February-winter-Orion deep-blue-stellar-light.

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.
