They are the same bean, they are only called different names by differnet regions of the country. For example, the main Indian Princess of the Hopi Tribe "KimKim Chickaauwa" calls them kidney beans, while in South Texas, Country Music singers like Eric Stone always refer to them as Pintos.
Kidney beans are larger than pinto beans and are solid red. Pinto beans got their name from the Spanish word "pintado," which means "painted." Hence, pinto ponies and pinto beans, which are smaller than kidney beans and are reddish brown and speckled. Kidney beans and pinto beans are not the same bean.
Vegkitchen.com reports that red beans will last in the refrigerator for up to a week, and in the freezer for up to 6 months. (Be careful if you have cooked with sausage or another type of meat. This will effect the storage time based on the type of meat. See http://www.cfsan.fda.gov/~dm/fttstore.html for the FDA's storage recommendations for various types of meats and protein foods.)

The dish, whether it contains beef, , fish, pork or vegetables with black beans (not as a sauce). Sometimes you will find the dish having the fragrance or flavour of black beans. I suspect that the the dish, with sauce, may created for a European/North American market. I feel sure that this comment could attract further conversations.
