What will a white gander with lavender geese give me?

[littlekatzz]

I recently acquired two lavender Sebastopol geese and will be getting a white male to breed to them .. I think I will get blue babies but wasn't quite sure and was hoping for some clarification. Though honestly I'll be happy with any color just curious

It depends on if the white is dominant, recessive or both, and what color is hiding behind the white.
