Which rabbit breed is characterized by a tan color and is abbreviated as "TN"?

The breed characterized by a tan color and abbreviated as "TN" is indeed the Tan rabbit. This breed is notable for its rich, warm tan color that can vary slightly in shade but maintains a consistent overall appearance. The Tan is distinct in its recognized color and pattern, typically having a darker coloration on the back and lighter shades on the belly and legs. This breed stands out not only for its unique color but also for its athletic build and lively personality.

The other breeds mentioned do not share this tan coloration or the abbreviation "TN." For instance, the Silver Marten is recognized for its darker coloration with silver tipping, while the Thrianta has a bright orange coat. The Standard Chinchilla, on the other hand, is known for its gray, blue-gray, or chinchilla color with a distinct type of fur. Therefore, these breeds do not fit the specific characteristic of being tan and abbreviated as "TN."
