Worldwide about 450 cattle breeds are known. Among other things they are characterized by a different coloring (pigmentation) and color distribution of the fur and the skin on the body surface. From white to brown and red-brown to black there are various graduations in the color of the fur. Some breeds show a single-color pigmentation, others are spotted or pinto. Depending on the intensity of the color differences of the skin on one hand and on the used leather color on the other, these various skin pigmentations shine through in dyed, naturalness-maintained leather. They create interesting color effects that do not make any kind of artificial post-processing necessary.
