Well it depends...if you want the highlights to stand out a lot then go for green. But if you want supplemental colors I would go for either purple or blue. No pink though, that would look good in blonde, not brown though.
It all seems funny to me but I'm old lol. I would have to say if it's something you are really going to , go with purple.

Purple or blue.... Please answer my question!
I will recommend blue or purple because you are brown hair.

For medium brown hair you should do purple and green but for dark or light brown do blue
