Vitiligo is a loss of pigment affecting portions of the coat, skin, and mane and tail.
Vitiligo spreads in irregular patches, and may grow or progress over a horse's life.
Vitiligo tends to affect the face, elbow area, and groin area first, but can affect any part of the horse.
It is acceptable to create white streaks in the mane/tail as the only expression of Vitiligo.
Vitiligo is a lack of pigmentation in the horse's coat and skin and will not be affected by Filigree, Opal, or Kintsugi.
