Hey, Vsauce. Michael here.

00:02

This appears blue. This appears yellow. And this appears green. Those of us with normal

00:10

color vision can probably agree. But that doesn't change the fact that color is an illusion.

00:19

Color, as we know it, does not exist in the outside world, beyond us, like gravity or

00:26

protons do. Instead, color is created inside our heads. Our brains convert a certain range

00:35

of the electromagnetic spectrum into color. I can measure the wavelength of radiation,

00:42

but I can't measure or observe the experience of a color inside your mind.

00:51

So, how do I know that when you and me look at a strawberry, and, in my brain, this perception

00:59

occurs, which I call "red," that, in your brain, a perception like this doesn't occur,

01:06

which you have, of course, also learned to call red. We both call it red. We communicate

01:12

effectively and walk away, never knowing just how different each of our internal experiences

01:19

really were.

01:22

Of course, we already know that not everybody sees color in exactly the same way. One example

01:28

would be color blindness. But we can diagnose and discuss these differences because people

01:34

with the conditions fail to see things that most of us can.

01:39

Conceivably though, there could be ways of seeing that we use that cause colors to look

01:45

differently in different people's minds, without altering their performances on any tests we

01:50

could come up with.

01:52

Of course, if that were the case, wouldn't some people think other colors look better

01:57

than others? Or that some colors were more complimentary of others? Well, yeah, but
