My RETF is BLUE. Is that normal?

Here is a picture with another Red-Eyed Leaf Frog. No enhancements, straight from my camera phone. Do you see many of these? Should i be worried? He also turns deep purple at night...

This looks normal. They will lighten and darken to match their surroundings. Since the leaf the frog isnon is dark the frog is darkening to blend in.
