The visual stimulation offered by both black and red markings amongst a herd of greyish cattle is not to be doubted. It might be expected, then, that it should be the pure black or red beasts which are most highly valued. This is not the case, for while the appreciation of well marked beasts should be understood in the context of a dull and pale landscape and herds preponderantly off-white in colour, it is the contrast of black and white or red and white in the single beast which provides the greatest aesthetic satisfaction. The individual beast, then, provides.
