Please identify my hamster breed for me!?

I was given a pair of dwarf hamsters by my friend but I have no idea what breed they are. They had a baby girl and I would like to know what breed this is. I have identified the color as lilac fawn, with a creamy and slight purplish tint. The size of a tennis ball, it has a plump round body with short legs and a furry sole. Fur is dense and thick. Face is not rat-like, rather round like a teddy bear, with a short flat nose. Blinks with both eyes. Intelligent. Can perceive height and responds to name. I want to know if this is Campbell, Winter white or pudding. Thanks!
