The Tan breed of rabbits is known for its distinct varieties based on color, and each variety typically has specific criteria outlined by breed standards. Black, blue, and chocolate are all recognized color varieties within the Tan breed. These colors have unique characteristics that contribute to the breed’s overall appearance and standards.
