Yup, at least on the outside.
Most people are familiar with the red radishes. Some may even have seen the ones that are white on the outside as well as the inside. There are, however, other varieties too, like these, that happen to be black on the outside. This was our first year growing them, and these are the Round Black Spanish Radish. When grown in cooler climates, they can get much larger, but we've got some planted now just for fun. Check this thing out!
