You're young, no need to dye your hair! Plus, so many people would kill for black hair. Lucky! But if you must dye your hair, keep it natural looking. Some warm chocolate and chestnut highlights weaved in around your face would be pretty for summer. Since people naturally get highlights outside, maybe your stylist could work in a few lighter strands as well (if brown isn't enough). But you don't want to go too light, or else it'll look tacky.
Also, NEVER dye your own hair if you're planning on going more than 2 shades darker or lighter. I've got horror stories from myself and friends. It's better to spend the extra cash and have a professional do it!
you have pale skin and probably could get away with having blond all over. I have blond highlights in my brown hair from time to time, especially in the summer to lift the overall look. I think a soft brown would look good on you or even blond would look good too.
