What color/coat is my goat? Is he a roan?

[Fangeddeer]

Been noticing the older my buckling gets the more interesting his markings get. Unlike any of his family, his stripe fades into tan and white. His root fur is black while his outer fur is a buckskin/dunskin looking tan. And his fur from his head is more deeper in color while it faded to white to his butt(can’t see it but his butt is white like a white tailed deer). Is this a special coloring? Will he loose it ? And does anyone know the name of it?
