Etymology

Salubrious
adjective

Latin salūbris, healthful — adjectival suffix -ous. As a color modifier, salubrious implies a clear-and-healthful-and-fresh quality, the crisp color of Alpine-and-Sea-air health-resort and Mediterranean-coast spa-and-thalassotherapy outdoor environment. Sits at the crisp-and-wholesome end of the grid, parallel to healthful and bracing in usage.

noun

The Chinese word for bluish-green jade — used for the deepest, most saturated jade-green color and the green of bì-yù (jadeite). The color refers to a polished imperial bì-yù cabochon: a saturated, slightly cool deep green-blue with the satin finish of fine jade. Cooler than midori.
