Ironclad Tang Forest

English compound iron + clad — referring to the 19th-century USS-Monitor and CSS-Virginia iron-armored warships. As a color modifier, ironclad implies a saturated-and-armored-and-impenetrable quality where the hue carries the visual weight of forged-iron armor-plate. Sits at the bold-and-fortified end of the grid, parallel to fortified and armored.

Old Norse tangi, sharp-projecting-taste. As a color modifier, tang implies a sharp-and-projecting-and-bright-bite quality, the visual register of Atlantic-and-Hebridean-sea-tang hand-sharp-and-projecting-and-bright-bite Atlantic-and-Hebridean-sea-tang-and-tide-pool-bite tang-and-sharp-and-projecting surfaces under Atlantic-and-Hebridean-sea-tang-and-tide-pool-bite Outer-Hebrides-and-North-Cornish-tide-pool sharp-bite-light. Sits at the modifier-and-flavor end of the grid, parallel to zest and tart 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.
