  I appreciate the skittles reference

    Is it a skittles reference or is it a reference to purple not being an actual color and thus not a part of the rainbow?

      the heck do you mean purple is not an actual colour??

        Purple, the color directly between red and blue, is a creation of your mind interpreting a band of light that triggers your red and blue sensing nerves, but no green is sensed. The actual band of light we can see goes from red to green to blue. Purple doesn’t fall between those colors, meaning it wouldn’t be included in a rainbow, and isn’t any “pure” light you could see, since it doesn’t fall on the spectrum.

        Don’t let them pee on your Cheerios. Purple is a color, just like magenta, pink, cyan, brown, and all the other “not in the rainbow/ROYGBIV” colors.

        Gatekeeping colors, I tell ya. Don’t let 'em get you burnt sienna with rage.

      I believe it’s indigo not purple there.

        Correct. Initially, Newton didn’t have indigo in his list for the visible spectrum, but he wanted seven colors instead of six because it matched up with the number of notes in music (and because he liked the number). So at some point there was discussion of removing indigo entirely because it’s kinda just a shade between blue and violet that the human eye just isn’t as good at distinguishing compared to the other colors. But the neat thing is that what people back in Newton’s time called blue and indigo is more akin to what we today call cyan and blue (they know this by looking at his labeled drawings of the light scattered by prisims). Now the spectral colors are: red, orange, yellow, green, cyan, blue, and violet.

      and thus not a part of the rainbow?

      Colour need not be on the rainbow. Colour is the human experience of colour which includes purple

      Our minds don’t care whether a color is pure or whether it is a mix. We see those colors.

      Like the berries there are technical definitions of colour that don’t mesh with the common definition

  Seeing the creator writing “actually” instead of “oh yeah?”
