Color issues going through receiver

[acole1]

I have a Pioneer VSX-912-K and tan colored skin or sand turns from tannish/red to green in blobs or lines. I've verified that it's the receiver causing the problem by plugging my TV into by Blu-ray player instead of the receiver, and the picture looks perfect. It's not a great example, but I have pictures (http://1drv.ms/1zSHp9I) showing a direct connection to the TV vs going through the receiver. You can see on the rock that there is greenish blobby-ness in one of the pictures.

Does anyone know what could be causing this and how to fix it? Let me know if more or better pictures would help.

Thanks!
