  7. My dictionary says that they have "black or dark-brown stripes on a whitish background." And, zebras sometimes have a light-colored belly with no stripes (usually the belly is striped, too). That would seem to settle the above question, although my encyclopedias mention black (or dark brown) and white stripes, and do not mention any background.

    I say they are white with dark brown stripes. From observation, the dominant color on their bellies is white if it does not have stripes.

  8. the above comments about zebra pelts are based on observation but not a large ammount of research. all of the above comments say that they are white with black stripes. the following is a quote from http://animals.howstuffworks.com/mammals/zebra-stripes1.htm

    "What color is a zebra? If you research this answer, you'll quickly discover many conflicting perspectives. But Lisa Smith, Curator of Large Mammals at Zoo Atlanta, reports that the coat is "often described as black with white stripes." This makes sense since the pattern is a result of pigment activation (black) and inhibition (white). That means black is the actual color of the fur, and the white patches are simply the areas that lack pigmentation [source: Camazine]."
    so it is safe to say that they are black with white stripes
