What a lovely collection of normals!
Normals come in a wide variety of colors and patterns, and you have some very lovely examples.
Kay is a nice reduced pattern normal with some nice banding and blushing along her back.
Brian is a fairly average normal, but he does carry the flecking known as "granite" is his markings. Judging from the fact that one of his babies has it as well, he may even be a genetic granite.
Brianna is a lovely reduced pattern normal girl with a partial black back.
Ace appears to have possibly inherited Brian's granite speckling, he's a pretty normal boy.
Jackson is a really sweet light normal with a terrific pattern and stellar blushing along his back. He'd be good bred to a light morph female like a fire or vanilla.
So there you have it my dear. One very nice collection of normals, each with their own special traits. Since you are looking to add a new female, I suggest getting a true morph and beginning to broaden your horizons.
