What color silkie is this?

[scarlethand]

I found someone selling silkie chicks somewhat close to me. They sent me some photos of the chicks. They have black and what i thought was buff but the pic was under a heat lamp. I asked if they are black and buff when messaging them and i think there is a slight language barrier. Here are the pics they sent me. Is the one white and the one buff?

Do you think they are about a week or so old?

Definitely not buff. It looks white but the exact color would depend on the parents’ color and genetics.
