Can you go into the Verizon store with a white iPhone and then ask for a black one?

Because I've been noticing people with the black iPhones have better picture quality so that's why I want to know. And tomorrow I might be going to the Verizon store to see if they can. Let me know please & thank you!

Yes as long as you have the receipt and 14 days hasn't passed since date of purchase and they charge a $35 stock fee
