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 Fancy Rat Genes for possible genetics.
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.

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 - 20 points for roaning, 15 points for markings, 10 points for top color, 5 points for blaze or headspot
Roan rats to be shown in any recognized color and come in Berkshire, Blaze Berkshire, or striped markings. Berkshire and Blaze Berkshire to conform to existing standards. Striped roan to have the body a pure clean white (devoid of creamy tinge or staining) and free from spots or brindling, with a colored stripe extending in an unbroken line from the head to the tail, be of moderate width, and be free of ragged edges or brindling. Striped Roans will also have a white blaze on the face to conform to existing standards. The color should be confined to the head and back only, not appearing on the underside (throat, chest, belly) or sides.
Roan is 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, though a ruby cast is common (to be accepted, but not desired).
Clearly distinct from existing varieties, Roans are born a solid color. During the first molt, 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 molt, 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, colored spots in white areas/white spots in colored areas; too little or too much white on face on Blazed versions; other faults as to respective markings; Striped Roan: stripe too wide or too narrow; stripe broken, ragged/brindled edges to the stripe, any suggestion of a Hood marking.

Note: a.k.a. Husky; always comes in Berkshire/Blaze Berkshire or Striped (with Blaze) markings. When Roan is bred with Self, you get Self, not various types of markings.

|SNOWFLAKE - To have small numerous spots of white on the belly with
as many spots of white on the backside as possible.
Genetics: unknown, doesn’t breed as normal dominant or recessive
Note: Appeared in Helen Pembrook’s rattery, Viking Rat & Mouse Nest (VRMN), in 2004. Has appeared in other ratteries since (showed up in Dutch rattery of René Baastians in 2008; called
stippeltjesin the Netherlands which means dots).

Read the information on Snowflake Rats.
“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.
