What will happen after my sunburn peels? Will color match skin?

It may. Over time, if you don't burn further, the skin tone should return to normal. I would recommend you use a sunscreen to protect you from further damage.
Yes.... ..Eventually. It may be lighter or darker than your normal skin color for awhile, however. Next time, apply a good sunscreen (spf 50) before going out in the sun - and don't try to get a tan all in one day.
