Which variety of rabbit has black and blue as recognized colors?

The Havana breed of rabbits is recognized for having a color variety that includes both black and blue. This breed is known for its compact size and has a soft, dense coat. The term "blue" refers to a diluted form of black, resulting in a grayish color that is also a standard for many rabbit breeds. The aesthetic appeal of the Havana, combined with the availability of these color varieties, makes it popular among breeders and show enthusiasts.

The other breeds listed do not typically include black and blue as recognized colors. For example, Dwarf Hotot is known for its white coat with black markings, and Himalayans feature a color pattern that focuses on points of darker colors on a lighter body, which does not include a blue variation. Dwarf Papillons are characterized by their distinctive marked patterns, and while they may come in various colors, black and blue are not recognized among them. Thus, selecting the Havana as the answer is justified based on its official color variety recognition.
