I looked at your pics, but I am not real sure so I hate to respond when I am really just guessing. So if I had to guess, I am leaning toward male. Just because the base of the tail by the vent is a little wider. I have a male that honestly, I was so convinced was a female! I kept telling the breeder I was so sure it was and it turned out to be male. Maybe wait a little bit, and post some more pics. Unfortunately, you cannot tell by colors at this early age.
