Why does green mean go? And other color conundrums

The world is full of color, but how do our eyes see it? In this episode we’ll explain how color vision works, complete with a journey to a jazz club in the back of your eye. We’ll also look at the cultural meanings of the color red, we’ll find out about a new type of blue, and we’ll find out why stoplights use green to mean go. Our Moment of Um tackles the question, “why are bees black and yellow?”
