Etymology

Sure
adjective

Old French seur, certain — used as a color modifier since the medieval period for hues that read as confident and stable. Sure red, sure blue: moderate saturation combined with optical commitment. Sits at the crisp-bucket center alongside steady and true.

Tea
noun

The processed leaves of Camellia sinensis, in either its assamica or sinensis variety. The color tea refers to the dried green tea leaves before brewing: a soft, slightly muted gray-green with the matte finish of withered and rolled foliage. Cooler than sage, warmer than matcha, with the ritual weight of a beverage drunk daily by half the world.
