According to the breed standard, Ragdoll cats with slightly rounded ears and blue eyes, but different fur color variations can be born.
There are three patterns: bicolor, mitted and colorpoint. The different color patterns of the fur come in six colors: gray-seal (blue), blue, chocolate, lilac, red and cream. The ends of the ears can be rounded, lynx, turtle or torbie (turtle and lynx).
So the number of possible color combinations is quite high. The US Cat Breeders Association (CFA) only accepts two-tone and van models, with the ends of the paws (gloves) and the tips of the ears pigmented differently from the rest of the fur as specific colors of the Ragdoll breed.
