What color will they be?

Jax is 15 months old now and I still don't know what color his eyes are going to be.  When he is in my bathroom, his eyes look really green.  Of course, my bathroom is decorated in green.  When he is in my family room they look like they could be blue or brown depending on how dark it is.  This morning I took a picture of him with the natural lighting from outside shining on his eyes.  I just don't know what color they are going to end up being!  I'm hoping green like his Nana.  What do you think?
