Etymology

Radiant
adjective

From the Latin radiare, to emit rays — used as a color word since the seventeenth century for hues that read as luminous and emitting. Radiant gold, radiant pink: the implication is high luminance combined with the optical impression of an outward light. Sits in the bright-bucket center alongside glowing.

Erba
noun

The Italian word for grass or herbs — used in erba luigia (lemon verbena) and erba cipollina (chives). Erba color refers to fresh-cut Tuscan lawn grass in May: a saturated, slightly cool yellow-green with the matte finish of fresh grass blades. The Italian cousin of meadow.
