As with the liver gsd the Blue german shepherd can come in different shades,most darken as they get older.
My personal preference is the black and liver gsd the blues shown here from other breeders so you can see what the colour looks like.
Above pictures of Blue puppies. BLUE IS A DILUTE GENE,
WHICH MEANS IT DILUTES the BLACK pigment to BLUE.
BOTH Parent's must CARRY the BLUE GENE to PRODUCE a BLUE PUPPY.
