Jokes aside, that's a good point - but if you think about it, why should we want to ingest something that provides no health value and only exists to make the food product look more visually appealing?
I don't know what kind of epidemiological effects dye has had in the long run, but it just makes no sense to me that as a society we have said "yeah, color our food so it looks more appealing, even though chemically it's probably not great for us". Just sort of odd, honestly.
Nutritious food doesn't always look amazing, and that's completely fine by me. I don't eat food because of the color, I eat food because it's healthy or tasty.
