Summary. 1  Pinto beans have dark reddish-brown marks on a brownish background. 2  This gives pinto beans a spotted or a âpaintedâ appearance. 3  Black beans, also known as turtle beans, are shiny-black in colour. 4  The richness of nutritional content in black beans is what makes them a better choice than pinto beans.
Black beans and other beans such as pinto beans, navy beans, and kidney beans are all known scientifically as Phaselous vulgaris. (This scientific name refers to the genus and species of the plant; navy, kidney, pinto, etc. are different varieties of beans, all found within the species vulgaris).
