Dark Red Brown 3-88, is a great colour, for I think maybe dark blondes, light browns and redheads. I wanted to take the ginger / orange out of my natural hair and cover up greys, this worked perfectly for it came out a deep red. I don't think this colour, would do much for dark brown or black hair except colour / cover and highlight the greys. (as you can't lighten dark hair too much, without stripping the dark colour first)
