What color are my kittens?

[blissfulkitties]

Kittens are Chinchilla, silver, mix????
Mom is a orange tabby persian and dad is a all white dearheart persian

As daddy is all white, at least half kittens will be all white too - depends if he is homozygot or heterozygot on white. If homozygot - ALL should be white.
I heterozygot - other colors may happen, for example mommas red and white.

What baffles me is two of them have a grayish rear end...

Might just be shadows with the picture, but it looks to me like you have some chinchillas . If dad was het for white, he could be carrying chinchilla and they would inherit this plus the colour gene he carries under the white. Non-white females will all be naughty torties!
