Some miscellaneous colors and markings of rats that have been produced by AFRMA breeders/seen at AFRMA shows but never standardized. There are many more out there.
See the AFRMA Official Color Standards Rat book for more.
Note: The pictures on this page are not meant to be true representatives of the animal’s color. Because of differences in monitors (CRT/LCD) and how the monitor is adjusted, the colors may be different. Seeing in person is always best.
|BALDIE - Color Pattern 15, Triangle 15, Color
Fading 10, Color 10
Baldie rats may be shown in any recognized color. Markings will be similar to Capped rats with a colored top of head and the rest of the body a pure clean white free from spots or brindling. The colored area to be clear of the nose tip and jaw line, extending a short way behind the ears. They will have a large white triangle between the eyes with a white line running from the point of the triangle to the white on the neck. Baldies are from Essex rats and color fading is normal.
[Accepted into Unstandardized April 28, 2007; removed from Accepted Proposed Unstd. December 1, 2012, and moved to Non-Recognized due to lack of entries.]
Note: Renamed from Baldie to Essex Capped in the N.F.R.S. in 2010.

|ENGLISH IRISH/IRISH - A common pet marking. They have both the marking
on the chest as well as the belly as the name implies, a.k.a. a lightly marked Berkshire. This is a marking that
will not be standardized.

|ROAN - Roan rats to be shown in any recognized color
and come in Berkshire or Blaze Berkshire markings. To be judged on evenness and symmetry of Roaning, not
amount of Roaning, as older animals will have more white hairs. White hairs shall be evenly distributed
throughout the coat, though a darker center line down the spine is acceptable but not desired. Roan not
to be confused with silvered animals. Eye color to match base color.
Clearly distinct from existing varieties, Roans are born a solid color. During the first moult, juvenile animals start to exhibit roaning. This is a steady increase in the amount of white hairs intermingling with the solid color, starting with the sides, face, and tail root, then working up to the nape of the neck and back. With each individual moult, the rat becomes progressively lighter, the final effect not fully complete until well into adulthood, at which point the animal is almost completely white.
Faults: Patchiness, brindling, uneven or insubstantial roaning.
Genetics: bred as a recessive
Note: a.k.a. Husky; always comes in Berkshire/Blaze Berkshire or Striped (with Blaze) markings.

“Tri-Color” rats have 2 distinct colors plus white.
Genetics: an anomaly in the genes of the individual rat causing a change in color in one or more spots/areas
Note: These so far are either somatic mosaics or chimeras and not reproducible.
