Multi-colored highlights

I've been thinking about it for awhile. My natural hair color is black and right now I have copper highlights in my hair and thinking about having some extra shades of copper added to my hair or at least something noticeable so you can recognize the added colors in the hair.

What do you guys think of this idea? How many of you actually do this? Any pictures? Help. Thanks.

i think you should change the base color to a dark brown. it'll look much better with the different color highlights, you could try dark blonde/light brown, caramel, or copper highlights
