problem with e500

I hope this is the right spot for this question.

I have an e500 and have had great success taking pics in fully automatic mode. I like to take sports photos of my

daughter's soccer team and, for the most part, they are good. I've recently decided to try getting into aperture

or shutter priority but when I switch to either, I my pictures are all "green". I would like to know wha tmight

be cause this anomoly or what other information i must provide to get some advice.

P.S. How do I attach a photo to a post?

Thanks in advance!
