How do I intentionally get the system to fade a bit before cut in. I think the stock order got messed up because next to the model number it says #1B, no idea what that means but im praying to god that doesnt mean black because I can't go longer with the system I have currently and my hair certainly is not black.

Granted, the new stock system doesnt necessarily look black but still needs a major color tone down, any techniques to do this?
