Neil deGrasse Tyson Explains How We See Colors

Video Description

Is that apple in your hand really red? Or is it another color? Or is it even a color? On this StarTalk explainer video, Neil deGrasse Tyson and comic co-host Chuck Nice are exploring how we see colors. Neil settles the “blue dress vs. gold dress” debate that took the internet by storm a few years back. We reflect on the relationship between scientific advancements and our physiological senses. You’ll learn why things are different colors. We discuss white light. Neil explains why, if you’re holding a red apple in your hand, the apple is not actually red. What happens if you take a red apple up to a light that has no red in it? What color would the apple be? All that, plus, we talk about “dark adaptation” and how it impacts the way we see colors in the dark.
