Color: it’s the ultimate kindergarten science lesson. The color wheel, the primary colors, the rainbow -- it’s fun AND educational! But when we learn about color in science class, and think back to what we learned in art class, we’re liable to get confused. How do colors make a wheel if the electromagnetic spectrum is a line? If red, blue, and green are the primary colors of light, why are red, blue, and yellow the primary colors of paint? And why are there three primary colors anyway? Society doesn’t answer these questions for us. I think they’re trying to keep it a secret. Like a conspiracy or something. While exploring these questions, we will touch on many other ways light comes into our world. These include: polarization of light (and how some animals can see it!), the spectra of stars and atoms, and lasers.
