Thats a very good post Not Guilty but let me ask you a question or two.Do you judge your color match by the mirror on your car?
Does your hair look great inside your house looking at it in the bathroom mirror but outside you see some red tone or glow?
You need to add purple color and it will be history.Get some red/gold correction plus,put 10 drops in a bowel with warm water,
mix it up,soak your hair in it for 30 minutes and rinse.Do this a few times and see the magic.
