Haircolor question

What are some good highlight/lowlight colors that compliment a dark chocolate brown? I'm a guy and I currently have dark chocolate brown hair (fauxhawk) with white blonde highlights. i'm going for a darker overall dramatic color and i was thinking about really dark brownish red lowlights but i'm not sure how that will look with chocolate brown, I dont want it too look too girly but still have some dimension at the same time. Should I go with dark auburn or a darker caramel color or something else?? Give me your best ideas ladies!

If you go with the red, the red will fade quickly as red always fades pretty fast. I think you would suit both colours, as your now colour is a rich chocolate brown colour, caramel hi lights would look good , however I think red high lites with a darker brown colour looks better.
