Well not all self based rabbits are 1 color because the torts are self and many of the shaded like sable are self with tan bodies and dark points. Self, tan, and agouti are pattern genes. Agouti makes your chestnut, opal, lynx, red, fawn... Aside for many reds which have a special gene an agouti has a light belly, inside the ears, around the eyes, and bands of different color on each hair shaft. Tan gene makes your otters and martens with tan pattern markings similar to agouti but no bands to the individual hairs in the coat. These are black otter, blue otter, chocolate otter, lilac otter, sable marten, and silver marten. Plus other less recognized combinations. Self makes each hair shaft all one color (there can be different colored hairs but each one is a single color) and does not have the white or tan markings of the other genes. So all basic black, blue, chocolate, lilac. Plus sables except martens and torts. All rabbits are one of those 3.
