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.
Kidney beans and other beans such as pinto beans, navy beans and black beans are known scientifically as Phaseolus vulgaris. They are referred to as common beans probably owing to the fact that they all derived from a common bean ancestor that originated in Peru.
