Roan is a coat pattern where white hairs are mixed with coloured hairs over most of the body. It is different from grey in a few ways: roan horses are roan from their first foal shed, and unlike greys don't become progressively lighter as they age. The head and points are generally solid coloured without the even mixture of white hairs seen on the body, and in many cases roaning on the legs ends with a distinctive upside-down V on the front of the knees. Roan summer and winter coats can appear quite different from one another.
When roan horses get skin injuries on their bodies, the scarred area grows back in their base coat colour without roaning, leaving visible marks.
Testing for roan can confirm your horses' colour, determine whether your horse has one or two copies of the gene, and identify when roan is there in combination with other colours or patterns that make it difficult to see.
This roan test works well for Quarter Horses and related breeds, and most pony breeds.
This roan test is NOT an indication of roan status for the following breeds:
