That one is more or less true. Light, (and by extension Rainbows) was arbitrarily cut up into 7 colors for religious purposes.Also, as a person that has been labeled "colorblind", I have always been suspicious that indigo is just a fake color made up by Big Color to make more money off of rainbows. I keep telling people: it's a pigment of your imagination.
