Natural white
-
Effects
- Skin: skin will be light pink under any white patterns
- Horns and hooves: hooves will be light where white leg markings connect [Horn & hoof color guide]
- Eye color: natural white generally doesn't affect eye color, because the markings shouldn't touch the eyes. [Eye color guide]
- White patterns cause a lack of color pigment in the coat, resulting in pink skin and white hairs. Skin will always be pink under white markings, even if blue dilute is present.
- Modifiers, Dilutions and Patterns must always go under white patterns, and are also not allowed to "appear" to go over white patterns.
- Can generally cause blue eyes if the white markings reach the eyes, unless otherwise specified.
- Hooves and horns will be lighter when affected by white.
- The minimum expression of each white pattern (except natural white which is optional) can only be reduced with Occlusion, which can partially or fully "turn off" or hide genes.
Appearance
Natural white markings are allowed on any horse, regardless of their genotype.
Natural white markings are limited to the face and legs, where the minimal allowed is completely hidden, and the maximal allowed is a wide blaze (not extending past the eyes) and white socks reaching the knees
The markings can be mixed and matched freely, e.g. a large white blaze with no white legs, or white socks of different shapes with no face markings present.
