I found their pics. Leo is Amber - agouti + chocolate. And the dutch marking is from Belle. So forget what I said above.
AA or Aa (probably AA because every non REW kit was amber), bb, CC or Cc, DD or Dd and who knows what the heck with E

and enen (because the white marking aint coming from him)
Belle carries vienna gene, probably is Vv. Thats where youre getting the dutch marking and blue in her eyes.
Betty White is your wild card. REW covers up everything else so you'll only know by what she produces.
