I would choose any female that also has a combination of those genes. Since all of the genes your male has are recessive, if you want any of his traits to show up, the female will also have to have those genes.
Your male has two copies of amel and two copies of anery (that's what makes him a snow), so I personally would choose a female that is het for those (which means she's only carrying one copy of those genes), and homo for his hets. So I think a pewter that is het snow would be a nice match for him. But really any female that has a combination of amel, anery, bloodred, and charcoal will be a great match for him.
