I take A LOT of photos of our dog and cat and the only way that I have found to fix the blue or green or sometimes even white eye is with a "pet eye pen". It looks like a felt tip marker and they sell them at craft stores or photo shops. You basically use it to fill in the eye color after the photo is printed. It takes some practice to make the eyes look normal and not like you just colored them in, but once you get the hang of it, it's an easy fix. I have a picture of our cat in our dining room and you can't tell that he ever looked like a demon in the original print--of course his name is Damien!
