What color should I dye my eyebrows?

I've decided that I'm going to start wearing wigs. I plan on wearing many different colored wigs (black, blonde, unnatural colors). However, I'm very pale and my eyebrows are naturally almost black. I'm afraid that this will make some of the wigs look cheap or really fake. What color should I dye my eyebrows that is a good all-round color that won't look weird with any color of wig?
