Thanks for the tip. I may have to try this. It is very difficult to get the right chocolate brown that I want -- not brassy or burgundy! My medium brown was fading and was looking too yellow/ashy so I thought some auburn tones mixed with neutral brown could warm it up. So using your technique, I would mix 1 bottle neutral medium/dark brown, 1 bottle light brown + auburn? I am afraid that auburn may look brassy!
