I think Red is my favorite color. When I was a kid it was blue.
That's interesting. Red pigment use goes back quite a bit - it's one of the first colors found in prehistoric art.
I wonder if they used blood back them for red?
I believe they used ochre. However, anything that contains the protein hemoglobin appears red. The same is true for anything with anthocyanins.
That is really interesting, please tell me more
Well, it is the hemoglobin in blood for instance that makes it appear red. Anthocyanins are found in berries and autumn leaves.
That is really cool we have so much history.
It's true! Cultures like the ancient Egyptians and Mayans colored there face red in ceremonies. I've even read that our vision has evolved to pay particular attention to red.
