Solid Cowl Ruby

Latin solidus, firm, dense — used as a color modifier since the seventeenth century for hues that read as continuous and unbroken: a solid blue is one with no variation across the surface. Implies high saturation combined with optical density. Sits in the bold-bucket alongside strong and robust, slightly more focused on uniformity.

Latin cuculla, monk's-hood-or-hood-of-habit. As a color modifier, cowl implies a monk's-hood-and-deeply-folded-hood quality, the visual register of Benedictine-and-Cistercian-monk's-cowl hand-monk's-hood-and-deeply-folded-hood Benedictine-and-Cistercian-monk's-cowl-and-Cluny-Abbey cowl-and-monk's-hood surfaces under Benedictine-and-Cistercian-monk's-cowl-and-Cluny-Abbey Cluny-and-Cîteaux-Abbey monastic-cloister-light. Sits at the modifier-and-textile end of the grid, parallel to cloak and frock 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.
