Is it me or do I see no sign of a male package? You have a female, unless my eyes are screwed. I've never heard of a 6 month old with no color either.
Some males turn out to be duds (very pale colors with very little painted looking colorations), some don't color up until they're 8-10 months old. Some are outstanding at the young age of 7 months... All depends on how lucky you got, and if you paid a lot of money for a future screaming breeder...etc...etc.
