Black, Chocolate, Blue, and Liver
Shiagan Herders are recognized in nearly any colors and patterns, however, they will always have a black-based starting point which is most reliably told by their nose color. This black base color is determined by two genes: The black or chocolate gene (BB, Bb, bb) and the dilution gene (DD, Dd, dd).
━━━━━━━━━━━━━━━━━━━━
Black
BB/DD, BB/Dd, Bb/DD, Bb/Dd
The dog's base color will be a dark, illustrious black.
▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂
Chocolate
bb/DD, bb/Dd
The dog's base color will be a warm brown.
▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂
Blue
BB/dd, Bb/dd
The dog's base color will be a solid ashen grey.

Lilac
bb/dd
The dog's base color will be a light grey-brown.

The Agouti Switch
A Herder's agouti markings are determined by two key factors: The K allele, which decides if the agouti markings will show, and the A allele, which decides what the dog's agouti markings actually are. The K allele, also known as dominant black, is like a switch, with K meaning the dog will not show it's agouti markings (even though it does have them genetically), kr meaning the dog will show it's agouti markings, but they will be brindle, and k meaning the dog's agouti markings will fully show.
━━━━━━━━━━━━━━━━━━━━
Solid
KK, Kkr
The dog's coat will not show Agouti.
▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂

▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂
Brindle
krkr, krk
The dog's coat will show it's agouti markings, but they will be brindled with black.
▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂
Agouti

The Agouti Type
A Herder's agouti markings are determined by two key factors: The K allele, which decides if the agouti markings will show, and the A allele, which decides what the dog's agouti markings actually are. The A allele, which comes in various forms, decides what shape the dog's agouti markings are, and is always carried, even when it is not shown.
━━━━━━━━━━━━━━━━━━━━
Clear Sable
AyAy, Ayaw
The dog's coat will show very little if any black, being predominantly red.
▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂
Tipped Sable

Shaded Sable
Aya

Wolf-Grey
awaw, awat, awa

▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂
Tan Points
atat, ata
The dog's coat will show red on it's eye pips, muzzle, throat, paws, inner hindlegs and the underside of it's tail.
▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂
Recessive Black
aa
The dog's coat is unable to produce red pigment, therefore not showing any markings.

Masks and Recessive Red
The extension gene usually simply displays a black mask over the front half of the dog, but when recessive (ee), the dog's coat becomes unable to produce black pigment, coloring the whole dog red.

ee
The dog's coat is unable to produce black pigment, turning it's fur to red.
