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.

Note: Renamed from Baldie to Essex Capped in the N.F.R.S. in 2010.
