Red Green or ????

I consider myself a reasonably intelligent person.  I hold down a good job, get a good salary, and have a reasonable amount of kudos shown to me in my chosen career.  However, while I feel pretty confident in my day to day, most days I find myself obsessing over the unanswerable.

I can literally spend hours and hours trying to answer these riddles, which are generally thrown into conversation by someone else, as a joke.  But there must be a little OCD in me somewhere, because I can't let go.  Luckily for me, google is my best friend (aside from the husband) and wiki is a distant but friendly relation. 

So todays question was "Is a red cabbage classified as a green vegetable?"

I would have said no, but it doesn't make it any less healthy than a green cabbage.  Turns out, it is considered a green veg, but with the added value of extra pigment that is Beta-Carotene.  So there you go.
