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.

Essentially, any time you see purple, you're seeing two different frequencies of light that your mind interprets as a single frequency.
