Microwaved artichoke cooked in water: water turns green hours later

I have twice noticed that when I microwave an artichoke in a bowl with a 1/2
inch of water in the bottom of it, that the liquid that remains is later a
pretty shade of green. Last night I did this, and specifically noticed that
the liquid was not green at the bottom of the bowl when I was done cooking
and had removed the artichoke to eat, but this morning saw that this water
had turned green.

What is happening here?

You're tripping, dude.

A chemical is being extracted by the cooking process, which does not
turn green until it has had the chance to oxidize. There are other
examples of phytochemicals changing colors on oxidation, Black
Walnut husks can make your hands turn brown, especially if light is
involved. Indigo is red until it gets exposed to air, when it turns
bluish.
