You can not sex those Tarantulas by colour. I hope you have good luck with it I dont like rose hairs ... to moody and when they get older they turn into pet rocks. But I see you have some tarantulas already so I am not gunna go to far into depth on rose hairs and sex if you dont want me to

Good luck with it, I my self wouldnt try handling it. Again they have mood swings and with turn mean in a split.

Have a good one,
