You mean the dull look? Still, it looks like one fantastic collection of tomatoes to me, could just sink my teeth into any of them.
My tomato cage experiment is not a success. You think some of yours lack lustre, you should see the ones out of the cage (surrounded by buble wrap but open at the top and bottom), they have callous-like skin. Brownish wrinkles and tough. Still good for cooking but not pretty at all.
