A color epithet describing true violet — the blue-violet hue that sits between blue and purple on the color spectrum, named for the genus Viola. It is more precisely blue-toned than purpureus and less purely blue than caeruleus. Appears as violaceus (masculine), violacea (feminine), or violaceum (neuter).
Etymology
From Latin violaceus, meaning "violet-colored," from viola (the violet flower).
Example
“Allium violaceum and Verbena violacea both produce the true blue-violet flowers that make this epithet one of the most precise and satisfying of the color vocabulary.”
