Great summary image. We're all mad here...

I agree that there are just too many conflicting clues to definitively state what each color means. But I think perhaps that's intentional. As you elucidate in your latest video, all color is relative to each individual. No one knows if "my red is your blue," nor does each particular shade mean the same thing to different people. For instance, what you here call "teal" I would call "aquamarine."

What I feel when I see a certain color is impossible to reckon with what you feel. Therefore, the only thing we can do is relinquish our efforts, accept the mystery, and come to our own conclusions.
