Aglow Throb Jade

Old English on-glōwan, on-glow — sharing root with glow and gleam. As a color modifier, aglow implies a saturated-and-lit-from-within quality, the bright color of fireplace-and-jack-o-lantern interior-glow-lit warm-light emission against ambient darkness. Sits at the bright-and-warm end of the grid, parallel to glowing and aflame in usage.

Middle English throbben, to-beat-strongly. As a color modifier, throb implies a pulsing-and-beating-and-rhythmic quality, the visual register of racing-pulse-and-temple-throb hand-pulsing-and-beating-and-rhythmic racing-pulse-and-temple-throb-and-heartbeat throbbed-and-pulsing-and-beating-and-rhythmic surfaces under racing-pulse-and-temple-throb-and-heartbeat fevered-and-quickened-and-rhythmic candlelit-bedside-light. Sits at the modifier-and-mood end of the grid, parallel to pang and pulse in usage.

Two minerals share the name: nephrite (a calcium-magnesium silicate, dominant in Chinese jade) and jadeite (a sodium-aluminum silicate, dominant in Burmese imperial jade). Both have been carved in China since at least the Neolithic. The color refers to high-quality apple-green jadeite: a saturated, slightly muted yellow-green with the waxy translucency of polished stone. Cooler than apple, warmer than mint, with the millennial cultural weight of yu, the stone of heaven.
