Onion

Description

A round edible bulb, Allium cepa, whose outer skins have been used to produce a dye. The dried skins are removed from the onion and boiled in water to produce shades of yellow, brown, and green. The flesh of onions makes a paler yellow and young sprouts give a vivid yellow. Historically, onion skins have been used for dyeing by the ancient Greeks, Persians, Egyptians, and African tribes.
