iPhone photos have blue tint

I haven't used the camera much but recently took some photos of flowers in my backyard and discovered most are tinted bluish. I had read in other forums and seen examples of this problem that others were having so decided to check mine out.

Should I return my phone to the Apple store, even though I am past the 14 day exchange date? What will they do? This is the only problem I have had with the phone and I don't want to get one that is worse.
