Variations in colors of haynas. Of course, not limited to these four, but this is the basic modifications. The first - it is the most common. Classic.
Can vary the color of the mane, that's fine. A norm for the whiskers - dark gray. All that is lighter - very poor, white - a complete nightmare. Albinos and light variations in haynas are relatively rare - the white color gives them a rejection, fear, and in some cultures, even disgust and hatred.
