Here are some possible scenarios:
* Albino: A raccoon with a complete lack of pigmentation would be white, but it would have pink eyes and a pink nose.
* Leucistic: This is a partial lack of pigmentation. A leucistic raccoon could have a white or tan coat, but it would still have dark eyes and a darker nose.
* Coat variations: Some raccoons may have lighter fur, even a tan color, but this is not considered a specific breed.
It's important to note that color variations in raccoons are not always indicative of a specific breed or genetic condition.
If you have seen a raccoon that you believe is white and tan, it is best to contact a wildlife expert or animal control to determine the best course of action.
