      Your brain made it up.

      Well, yeah, but our brains make up every color. Our experiences of color are nothing more than a facet of our brains’ interpretations of light information. It’s all in our heads.

      Magenta is a primary color (not red). You can’t mix non-magenta red paint with blue paint to get purple.
