A cream legbar should have a much more muted color. I believe, although they will have similar markings the Bielies are red based and the cream legbars are silver based (I may be totally wrong, I am terrible with genetics). See links below for green fire farms cream legbar and bielefelder examples:

It was mentioned at some point that there is a silver based type of Bielefelder in existence.
