Good looking tomatoes Irwin.
I like the colors other than red better because as Scott said they are less acic and they do all have a little different flavor from each other.
I grow a variety of colors myself, its fun to see them all mixed in the vegetable garden.
I grow multi colored carrots, broccoli, cauliflower and potatoes as well.
I know, I know I am so wild and crazy, I have also been known to run with scissors on occasion.
