White hatchback, what color rims?

Black,

You have many excellent options here for your car. Some tire and wheel sites will allow you to upload a photo of your vehicle and then you can place the wheels on your car digitally to see how it looks. White wheels might look nice, also white is an excellent color because it doesn't show all the dirt. Chrome wheels are nice as well but might be a bit flashy.

My vote is for lime green. Along with a lime green pin stripe.

I recommend using PlastiDip to paint your wheels. If you don't like it, you can just peel it off. Go to dipyourcar.com they have many different colors of paint to choose from.
