Brown juice?

I tried to give Avery orange juice this morning, since she'd been sick, and its good for colds. I don't think she liked it. She immediately said "A want apple juice!" I told her orange juice was yummy, to finish it and I would give her more Apple juice. Now she is saying, "A want brown apple juice. Smart huh? How do you explain orange juice is orange but apple juice is still apple, etc...
