If you breed two different colors together (with the exceptions of Blue, Black, and Splash), the result is unknown, especially when crossing white with another color as white can hide other color genes that the bird is carrying.
When Seramas (or any breed for that matter) don't breed true it means they will not produce offspring of identical color.
