What a great video!
Should be mandatory viewing for anyone who feels the urge to expound on colour correctness!
Because the vast majority of us have eyes, we believe we are experts at seeing: we all have arms, but very few will throw that touchdown pass!
I especially like the references to language and culture. This is true of most of what we see. The degree to which we see 'the same thing' has as much to do with how close our languages and cultures and experiences are.
The same is true for other ideas, and many would be distraugt by the fact that certain concepts, such as the judeo-christian concept of love, did not even exist in some other cultures. There were no words, so it simply did not exist!
They had and still do have other words, for concepts that we can only approximate, such as the Japanese word, amae.
On a sadder note, now that I'm 66, and because of my relationship with visual design and cognition throughout my career, I try to forget that as I age, I cannot be sure that I actually see colours the same as the younger folks in this forum. In fact, it is almost a certainty that I am less able to finely discriminate between green and blue. And it will only get worse.
Good news for me though, with my focus on desert vehicles, is that the perception of yellow and orange are much less affected!
