How are red, yellow, and blue made for paint?

What does painting the most splendid sunset and the most radiant rainbow have in common? They both require lots of beautiful paint colors! We can blend colors to make orange, green, and purple, but how do we make primary colors like red, yellow, and blue? We asked color science professor Stephen Westland to help us find the answer. Got a question that you’re dye-ing to get answered? Send it to us at BrainsOn.org/contact, and we’ll help illuminate the answer! See omnystudio.com/listener for privacy information.
