Imperial Torrent Ruby

From the Latin imperialis, of the empire — applied to color since the medieval period for the hues reserved for sovereigns and empires: imperial purple of Tyrian dye, imperial yellow of Ming-dynasty porcelain. As a modifier, imperial implies saturation combined with the institutional weight of a color owned by a court. Sits in the bold-and-deep corner, alongside royal.

Latin torrens, rushing-or-burning-stream. As a color modifier, torrent implies a rushing-and-deluge-and-flash-flood quality, the visual register of Alpine-and-Pyrenean-torrent hand-rushing-and-deluge-and-flash-flood Alpine-and-Pyrenean-torrent-and-monsoon-deluge torrent-and-rushing-and-deluge surfaces under Alpine-and-Pyrenean-torrent-and-monsoon-deluge Alpine-Dolomites-and-Pyrenean-cirque deluge-rushing-water-light. Sits at the modifier-and-weather end of the grid, parallel to rain and thaw in usage.

From the Latin ruber — simply, red. The gemstone is a chromium-tinged corundum, harder than anything in nature except diamond, and so saturated that a fine Burmese pigeon's blood ruby at auction outpaces a comparable diamond by weight. The color borrows the gem's confidence: a clear, glassy red without the brown of garnet or the blue of crimson.
