GSD color question

The dilute of black in GSD will give you a Liver colored GSD. Think Chocolate Lab. I know this because I had one for 13 years! The was solid liver. If not for the dilute gene he would have been a solid blk dog. There is also Liver and Tan.

This is a Red Sable GSD...pure bred. Maybe this is what you meant.

No, I mean blue. Blue and red are caused by two different modifiers on different alleles and locations. Blue is a dilute of Black, red is a masking of all black. All colors genetically start out as black and the different colors/patterns are various combinations of modifiers from there.
4GSD - Coat Colours
There are some blue dogs pictured there, along with some liver dogs further down.
The clear sable does look close to what most people would consider a "fawn" but I believe the person I'm asking the question for was thinking in terms of what is called Isabella in Dobes.

And this...
The type of pigment synthesized in mammalian hair, yellow–red pheomelanin or black–brown eumelanin, depends on the interaction between Agouti protein and the Melanocortin 1 receptor. Although the genetics of pigmentation is broadly conserved across most mammalian species, pigment type-switching in domestic dogs is unusual because a yellow–tan coat with variable amounts of dark hair is thought to be caused by an allele of the Agouti locus referred to as fawn or sable (ay). In a large survey covering thirty seven breeds, we identified an Agouti allele with two missense alterations, A82S and R83H, which was present (heterozygous or homozygous) in 41 dogs (22 breeds) with a fawn or sable coat, but was absent from 16 dogs (8 breeds) with a black-and-tan or tricolor phenotype. In an additional 33 dogs (14 breeds) with a eumelanic coat, 8 (German Shepherd Dogs, Groenendaels, Schipperkes, or Shetland Sheepdogs) were homozygous for a previously reported mutation, non-agouti R96C; the remainder are likely to have carried dominant black, which is independent of and epistatic to Agouti. This work resolves some of the complexity in dog coat color genetics and provides diagnostic opportunities and practical guidelines for breeders.

Ok...here is my last post on this...lol. This lady knows her gene dilution of GSDs.
