Why is a watermelon green on the outside?

Anonymous asks, "Hi Friendly! I have a question that's bugging me for a while now: why are watermelons green on the outside?"

Um . . . Chlorophylls on the outside, flavanoids on the inside? I pirated that guess of a pigmented answer from here.

I did study botany for a year back in my collage days, but that stuff is just a really really distant memory now. Probably a better question for the people at whataboutwatermelon.com. ;)


(Why am I remembering something crazy I once said about watermelons on a Ravenwood Radio podcast? What was that?)
