          UNDERSTANDING COAT COLORS
          Pigmentation in cat fur varies from
          an even distribution along the hair shaft,
          which produces a solid-color coat, to no
          pigment at all, which produces white fur.
          A solid coat’s color is determined by the
          density of the pigment in its hairs. Diluted
          red, for example, becomes cream. If just the
          end of each hair has color, the coat is
          tipped, shaded, or smoke, depending on
          exactly how much of the shaft holds color.
          Ticked shafts with alternating dark and light
          bands give a tabby color called agouti.  Solid  Tipped   Shaded       Smoke         Ticked
