There are three mystical eye colors for a werewolf or a coyote: bright gold, steel blue and red. Their rank and power are also reflected by their eye color.

GOLD :...

Every canine shapeshifter, born or transformed, starts with the gold eyes.

BLUE:...

The eyes will change from gold to blue after one takes an innocent human life.

RED:....

A canine shapeshifter with red eyes is an alpha. When one rises to Alpha status, their eye color, gold or blue, will change to red.
