Despite our many differences, there are certain things we humans can collectively agree upon: Brussels sprouts are gross, nobody should put honking horn sound effects in songs, and if Donald Trump tasted like something, it would be a withered 7-11 hot dog.

Now, watch how this limitation affects their actual perception of color:
