That there are purple carrots?

I shit you not, these aren't even some weird cultivar. There are purple carrots and the purple on the outside comes from anthrocyanin, the same thing that makes blueberries blue and purple pansies violet. The orange carrot has only been around since the 17th century, when the Dutch bred it to show support of the House of Orange.

A note to historical (pre 17th century, of course,) and medieval fiction writers: If your carrots are orange on the outside, you're doing it wrong!

Did you know that there are also purple potatoes?

Anthrocyanin again, though these are a weird cultivar.

Did you know that if you eat any number of these lovely vegetables containing anthrocyanin, or blueberries, blackberries, beets, or eggplant, your teeth and lips will not be stained purple, and people will not avoid you for half an hour as if you are a purple people eater?

Eat just one cookie from the cafeteria covered in "blueberry purple" frosting, however...
