In the kitchen cabinet is a bag of oranges for morning juice. Each orange is stamped “Color Added.” The dyeing of an orange, to make it orange, is man’s most impudent gesture to date. It is really an appalling piece of effrontery, carrying the clear implication that Nature doesn’t know what she is up to. I think an orange, dyed orange, is as repulsive as a pine cone painted green. I think it is about as ugly a thing as I have ever seen, and it seems hard to believe that here, within ten miles, probably, of the trees that bore the fruit, I can’t buy an orange that somebody hasn’t smeared with paint. But I doubt that there are many who feel that way about it, because fraudulence has become a national virtue and is well thought of in many circles.–E. B. White, “On a Florida Key”
Not to distract from White's excellent point, but I wonder if the change from eating oranges to other varieties like tangerines or satsuma oranges is caused by something other than convienece. For example, it is only in the last 5 or so years that I could commonly find (even in CA) other varietes of citrus besides the standard Navel Orange. You can buy clementines, honey tangeriense, budda's fingers, blood oranges, and so forth, all in your local market.
