Nothing really new (Score 1)

I worked in a produce department for two years. In that time I saw some really strange fruits and veggies come through and purple potatoes were one of them. As I recall, only the skin is purple, with a slight tinge on the actual "meat" of the potato. You have to remember, there's a lot of varieties of potatoes. Russet, Yellows, Golds, Blues, Purples, Reds, the list goes on.
