What color hair will Tristan have?

Well, we have come to that point where Tristan is losing his "baby" hair and getting a new set. I have noticed over the past few weeks that his hair was thinning out but it is really noticeable when you compare a picture from Novemeber to his recent pictures. Originally his hair was medium to dark brownwith long sideburns, but he is now going bald! His new hair is starting to grow in slowly and appears to be much lighter...I wonder, are we going to have a little towhead? My prediction is that his new set of hair is going to be a dirty blonde/light brown color and eventually get darker. I guess only time will tell...check out the comparison below for now.
