What is it you want to know?
There are 4 patterns in the GSD. In order of most dominant to most recessive:
Everything else is merely a variation on those themes, governed by different genes that determine, for example, extension of black pigment (making for a lighter or darker black/tan or sable) or hue of the tan pigment (black/red vs black/tan vs black/silver, etc...) and other minor factors.
Liver and blue are dilutes that affect black pigment, and can occur in any pattern.
White is a masking gene that essentially trumps the regular color gene, causing the dog to be all white even though it still possesses regular color genes as well.
Panda appears to be a spontaneous mutation that cropped up recently, creating a tri-colored dog.
