Panther chameleon to sex

[Thatbingo]

Hello all,
I have a cute little panther that is about 4-5 months old. I was told by my Breeder that my Cham is a boy but I just wanted to double check. Here a few pictures, one when I got him/her about 3 months ago and a couple others more recent. I just can’t tell if he/she is a boy or girl. Any help would be appreciated! Thanks

Could you post some pictures of the tail base? In the first picture it almost looks female, but they show red in the next two.
