Are We Seeing the Same Colors?

These are some colors we see:

Obivously, for everyone of us, the first one is red, the second one is blue, and the third one is green…right? Right? When I was a child, one fine day I had a weird thought: what if we actually are not seeing the same colors? What if for a group of people, let’s call them the Anders (German for “the different”), the boxes look like this:

Again, the first box is red for the Anders too, but the red they see doesn’t look like the red we see. It looks like what green looks to others!

I remember this occured to me when I was in like sixth grade, it was 2016. I felt like I had discovered a very amazing concept! I wasn’t willing to share it so early and wanted to do some more research before revealing my new discovery (😅) to the world. But before I could do that, I came across this video from Vsauce titled Is Your Red The Same as My Red?. I was both happy and sad. Happy because something I had originally thought of was not completely off track, sad because it wasn’t really something that I had uniquely found.

Well, what do you think? Are we seeing the same colors?
