I'm really not sure, but even China held it as an important color. They used it to color early pottery.
My favorite color is red, I love it and try to get everything in red! Neat, how do you feel about the color next to it on the spectrum of light, orange? Or the one opposite it, violet? Not a fan, I rather learn more about red if you know anything. Red was pained on the faces of the Ancient Egyptians and also the Mayans during their ceremonies. I haven't heard that.  Is red the most common color for people to like?
It was also an important colour in China, where it was used to colour early pottery and later the gates and walls of palaces.
