A Cabbage by Any Other Name

What colour would you say this is?

I asked Bob to pick up a green cabbage on his way home from work, and he called me from the store in a bit of confusion. Apparently, the Canadian "green" cabbage I was after is called "white"cabbage here--who knew? Green or white, roasted and drizzled with the sauce I had made for the pork, the cabbage made the perfect dinner accompaniment.
