Roan
RnRn / nRn
Effects
- Skin: no effect on skin
- Horns and hooves: no effect on hoof color [Horn & hoof color guide]
- Eye color: no effect on eye color [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
Roan causes the coat on the body to have evenly mixed white and colored hairs.
At minimal expression roan needs to have subtle roaning starting around the rear.
Roan does not affect the mane or tail, and generally avoids the head and legs
The amount of white hairs varies between each horse, as well as the "even-ness" - it can appear slightly varnished or textured.

Optional effect: Corn spots
Corn spots on roan causes small "holes" in the roaning where the base coat is visible.
Additionally, on roaned horses scars and injuries can have the fur grow back in the same color as the base coat, without roaning.

Optional effect: Reverse dapples
Roan can have a reversed dapple effect, with dark dapple spots on the roaned areas. These dapples can be anywhere from just subtly darker, to completely showing the basecoat underneath. A roan with heavy dapple effect can appear as white lacing on the coat, as shown on the third example.
