IRISH - Irish rats may be shown in any recognized color. The top color is to be judged as to the respective color. Distinctive markings are the white underside, with four white feet and a white tail tip. The under marking should be a pure clean white, of moderate size and as even in shape as possible, not extending onto the legs, sides, or chest. The white feet should resemble the stops on a Dutch rabbit. The tail should be colored for most of its length, with a white tip of no more than one-fourth of its total length.

ESSEX - To be recognized in any standard color, remembering that the effect of the gene responsible is to lighten the top color. The darkest area is along the spine, becoming less intense down the sides of the animal. The gradual fading of color continues onto the belly which is off white, with no spotting of darker color. When viewed from above, the fading effect should be symmetrical, having no clear demarcation. The fading effect also to be seen on the legs so that the feet are also off white. There should be no obvious patches of contrasting color. Pied tails not to be penalized. A head spot is essential; this must be well defined, centrally placed on the forehead and symmetrical. Genetics: Unproven lethal dominant gene on H locus tentatively named Hro * (N.F.R.S.; accepted 4-30-05)
