What is a good name for my female blue pitbull puppy?

She is 5 weeks old, im not sure if she is gonna have blue eyes or not she does at the moment but her momma and daddy have yellow eyes im pretty sure she will too. She is a light silver looking blue with white on her feet and cheast and a small thin strip on her snout. The names im liking are saphirre, azura, luna, and lil mama. I just dont know if any of these are good enough yet so please help with some more names like that and related to the color blue and whatever else!! thanks :)
