Color is "natural black" meaning it is not blue black, not brassy, not jet black, simply black but don't get me wrong, it's not dull and not too shiny either. This is the first time dyeing my hair black. This color took my auburn/dark natural brown hair to the Asian/Indian black hair (like my family) and it looks very natural. I love it. Doesn't look funny in daylight or sunlight either. Don't really yet know what tones/highlights mean but I could care less, again, it turned out great. It has a mild pleasant scent, no one will notice you colored by the scent, it was easy to apply and the after conditioner is wonderful. A little goes a long way. Grab two bottles just in case, one worked for me but if my hair grows a few inches I will need more. My hair is thick, past shoulders yet not quite to the middle of my back.
