Whats the best color highlight for medium length black hair?

My hair is not layered. But would highlights look better if my hair was layered?Whats the best color highlight for medium length black hair?
I think that maroonish brown color for highlights would look good for black hair. If you get layered hair even better they would show up in any hair style hope this helps.Whats the best color highlight for medium length black hair?
i would say a deep red ^_^
blonde


or


red
keep your black hair all one color and just get it layered. plain black hair looks really sharp and highlighting it would make it look tacky
