Blue headed frog

New to forum. Trying to figure out what kind of frog this is. I let my pool go over the winter and its green. Just starting to clean it and this blue headed frog is in it. Can't seem to catch him. Getting ready to,add chlorine so I assume he will get out.
What do you know about this frog?
I'm trying to attach pic.

Very cool! That looks to be an axanthic (lacking yellow pigment) green frog! Without the yellow pigment, the green head of a green frog would look blue just like that. Awesome! Please consider submitting this unusual find to Herpmapper.org!

That is one cool picture Coco-lab. Thanks for sharing that with all of us.

I was going to ask what color mutation of Rana clamitans that might. However, you already answered the question for me. So, thank you, very very much!

I was going to suggest that too. But, you beat me to that as well. You clearly are ahead of the game!

Nice find!
