I think Onyx is a blue roan. Born black..but i noticed some white hairs in her tail yesterday so did a body clip. She definetley has minimal white (almost silver) hairs scattered about on her body. I was hoping for a blue roan..mom is sorrel roan, dad is homozygous black, but was certain she was a black and got quite accustomed to her being a rich black like her daddy. Does the white mean roan?
