Clean Friar Topaz

Old English clǣne, pure, free of dirt — used as a color modifier since the medieval period for hues that read as crisp and uncontaminated by other pigments. Clean white, clean blue: moderate saturation combined with optical clarity. Sits at the crisp-bucket center alongside clear and true.

Old French frere, brother. As a color modifier, friar implies a Franciscan-and-Dominican-mendicant quality, the visual register of Franciscan-and-Dominican-Friar hand-spun robe-and-rope-belt-and-sandal Franciscan-and-Dominican-mendicant-and-preaching surfaces under Franciscan-and-Dominican mendicant-Friar hand-spun-robe-and-sandal preaching-tour light. Sits at the modifier-and-cultural end of the grid, parallel to monk and nun in usage.

A fluorine aluminum silicate gem, hardness 8 on the Mohs scale, mined for centuries in Ouro Preto, Brazil. Imperial topaz is the prized variety: a warm, slightly pink-shifted gold-orange with the high refractive index of a quality cut stone. Cooler than amber, brighter than honey, with the gem's signature internal fire when held to light. Named for the island of Topazos in the Red Sea, though that source produced peridot instead.
