Royal Zeus Forest

The blue of European royal court dress and regalia from the late seventeenth century forward — the color of British peers' robes, French royal sashes, the lining of the crown-jewel cases. The color refers to a saturated, slightly violet-shifted blue with the matte finish of velvet or melton wool dyed to maximum intensity: deeper than cornflower, warmer than ultramarine, with the heraldic weight of a color reserved for monarchs and the official Crown.

Greek Ζεύς, king-of-the-Olympian-gods. As a color modifier, zeus implies a thunderbolt-and-king-of-gods-and-Olympian quality, the visual register of Olympian-Zeus-and-Phidias-Pheidias-statue hand-thunderbolt-and-king-of-gods-and-Olympian Olympian-Zeus-and-Phidias-statue-and-Mount-Olympus zeus-and-thunderbolt-and-king-of-gods-and-Olympian surfaces under Olympian-Zeus-and-Phidias-statue-and-Mount-Olympus Pheidias-chryselephantine-and-Olympia thunder-cloud-light. Sits at the modifier-and-myth end of the grid, parallel to hera and atlas 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.
