Here I show roans. Using the previous charts (bay, black, and sorrel with their dilutes), you can apply the "base coat" to the roaning.
Roans are categorized by an even mixture of the base coat & white hairs throughout the body. The white hairs are not present on the bottom of the legs or the face, giving them a darker appearance. Skunk tails and guard hairs may be present in the mane and tail.
