Exchanging an opened product

So I bought the iPad Magic Keyboard in black 3 days ago, and after some use and research, I found that the black variant is a dust magnet and from what I've experienced, has already stained a bit on the bottom. However, I now want to exchange this keyboard for the white variant but I'm not sure if I can as I've already opened the black one but has have kept all packaging, pamphlets and protective plastics intact.

Would my local Apple Store accept an exchange request for a product that was opened within 14 days?
