Mixed variation or?

[lilwanderer]

I have these two silkies, one acts like a roo but thats besides the point. Wondering what color they are or are they just a mixed variety and not a standard color.
One is white with buff coloring here and there, the other looks partridge- Maybe poor quality?

The black/gold one might be a gold birchen

They’re mixed variety, like a lot of silkies are. They’ll probably turn out to be mostly white and either mostly buff or mostly partridge.
