Seriously? I learned the mnemonic, Roy G. Biv, when I was a kid in school. Of course they have decided not to include indigo as a separate color any more. That kind of messes up Roy's name.
But you can only get pink by mixing white with red. There is no pink in the visible spectrum.

I went and watched your link. I definitely wouldn't have thought of pink as minus green. That doesn't really sound right since you make it using red and white, and white light is a mixture of all the colors in the visible spectrum.
