Allium cepa Onion Skins will give you shades of red browns to gold yellows and oranges. Mordants are not neccessary for fastness but will alter the shades - Alum for yellows, iron for olive greens. Best results will be acheived on wool and silk - paler, duller shades on cotton using Aluminium Acetate as a mordant.
