Hi Dave. I don't think you have gotten any responses because I don't think anyone is certain for sure, myself included! With the 4 pics you posted on the other thread I would say female, with the exception of the 2nd photo which I would have said male if posted by itself! In most of the pics the tail is thin and there is somewhat of an indent that the females posess. If you got it from a breeder who is reputable, I would take their word for it. Mistakes are made, but not too often for people who breed for a living. And you are right, you cannot go by color at this age. Hopefully, some others will give their opinions and if not only time will tell!
