The colors of vegetables always fascinate me. Through our produce, we have the full visible spectrum of pigments, but many lie in the beta-carotene spectrum which controls the amount of red pigment. I find them beautiful and a reminder that our natural world provides much more variety in foodstuffs than we are used to seeing in the store. Those are usually bred for their tolerance to shipping — not flavor or beauty!
Tomatoes are one of my favorite vegetables (fruits!) and the size and shape of them is varied and entertaining sometimes. This illustrates both the breadth of color and shape variation.
