Smoldering Wax Emerald

The progressive participle of smolder, to burn slowly without flame. Used as a color word since the late nineteenth century for the deep reds and oranges of barely-flame coal — the warm saturated darks where the heat is internal rather than emitted. Sits in the bold-and-warm corner, slightly less luminous than burning and slightly less calm than rich.

Old English weax, beeswax. As a color modifier, wax implies a translucent-and-warm quality, the visual register of beeswax-and-paraffin hand-rolled-and-poured candle-and-wax-tablet beeswax-and-paraffin candle-and-wax-tablet surfaces under candlelit-beeswax-and-paraffin warm-glow. Sits at the modifier-and-texture end of the grid, parallel to waxen and honey in usage.

A chromium-tinged variety of beryl — the gemstone mined from the Cleopatra-era Mons Smaragdus in Egypt, the Muzo deposits of Colombia, and the Sandawana mines of Zimbabwe. Emerald green refers to a high-clarity faceted emerald with strong color saturation: a saturated, slightly blue-shifted green with the gem's signature internal life. Cooler than fern, warmer than teal, with the heraldic weight of two thousand years of royal favor.
