BUT. Manufacturers of paint give their colours names. You may find that another manufacturer calls their paint colour Azure but both may turn out to be inconsistent with each other.
Do the instructions give a manufacturer code number for Humbrol or another etc. ?. This can then be cross matched. Vallejo have a file which cross matches their paint colours with all the leading manufacturers. If you have the number let me have it & I will do a match if possible.
By the way when I have ordered form Johns Shop above the stuff comes down next day.
