Ok, this may be a bit lengthy, but I'll try to be concise.
Silver pied x Silver pied will result in offspring of the following
Silver pied, dark pied white-eyed and white white-eyed.
Silver pied is the combination of one white gene, one pied gene and two white-eyed genes.
One parent must pass on the one copy of the white and one of the copies of white-eye
The other parent must pass on the one pied gene and the other white eyed gene.
If a bird only possess one white gene, one pied gene and one white-eyed gene, it is considered to be Pied White-eyed
A white bird has two copies of the white gene, a pied bird carries one copy of the white gene and one copy of the pied gene (no bird can carry two of both genes or two of one and one of the other - I hope this makes sense), and a dark pied bird carries two copies of the pied gene - often showing up as a white throat patch and some white flight feathers.
Now, White x Silver pied would produce White White-eyed (single gene of the white eye) and Pied White-eyed. Only one copy of the white-eyed gene is passed on because only one parent has it.
To explain white-eyed. This gene is considered partially or co-dominant. A bird can have one or two copies of the gene and still express it. A male having one copy of the white-eyed gene may only show some "white eyes" in his tail, where a male having two copies of the gene will show all or nearly all "white eyes in his tail. (I will try and send you some web links of these examples if you want).
The white gene, when a bird carries two copies, will mask all other phenotypes. This means you could have a white blackshoulder white eyed bird, but it will only look like a white bird. It also means you could have a bird that is technically another colour - for example if you breed Bronze Pied to Bronze Pied, you will get some white birds. If you breed these white birds to a regular bronze bird, you will get more bronze birds. The white birds are essentially bronze birds but masked with white.
I hope this helps, and that the translator is accurate for you to comprehend what I have tried to explain.
