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.
