Ok so we all know that the Czech Wolfdogs standard states that the wolfdog should be "wolf sable" in my mind constitutes a dog this colour :
(I can't remember who owns this dog, its from this site, if you want me to remove it I will! Same for all the other photos)

Light Grey with Dark Grey Shading, lightish tan on the face and legs, then lighter white paws, muzzle, belly etc : (Diagram yay!)
Excuse the badly drawn dog, I just really need to learn genetics ok so Wolf Sable, Greyish and Tan Ok this is taken from
http://www.huskycolors.com/genetic.html
ay Restricts dark pigment; makes sable or tan. Sable
B Black. Must be present for black to appear anywhere on the dog. Black, Grey, Wolf Grey, Agouti, Sable, Isabella White
ty Sable or dominant yellow. Epistatic to B-E when T is present which produces black. Sable, ?
so anyone have any idea what the genetics would be for the STANDARD wolf grey/sable Czech Wolfdog.
Ok next part is the dogs that are more Silver / Red these dogs must be affected by modifiers? so what would there genetics be? Is it dilution in silvers? Or just washed out bad colour?
Silver:

Noting the lighter silver and the lack of tan
Red:
And how about the really darkish dogs:

(believe it or not those colours were taken directly from the photo!)
I also constructed a colour table too :
You can really see the differences in colours there
