I always learned “ROYGBIV” as the colors of the rainbow. Red, orange, yellow, blue, indigo, violet.

What’s up with the last two? Isn’t indigo basically just dark blue? Why is it violet and not purple? Can’t it just be “ROYGBP”?

    It doesn’t contain pink or brown. Some of the colours we see are how we register a mixture of light frequencies, whereas each point in the rainbow is just a single frequency.

      What a phantastic thread!

      We have had linguistics, sociology, physics and now biology in the form of colour perception so far.

      Cross domain discussions are great! :-)
