history: red is one of the best colors Interesting, is it because its on the end of the visible light spectrum? yes, and really plainly it is pretty awesome, and does have meaning behind it I'm not aware of the meanings, yet I know that during the Renaissance, the rich and nobles had brilliant red costumes dyed with kermes as well as cochineal. I wonder if there is a significant meaning today? I can't say, but ever hear of the Rayleigh scattering? It's what causes the red sky during sunset. Interesting, do you happen to know why Mars looks orange to us? That would be due to the iron oxides and it actually gives off the red color. I guess I did not realize that mars was red, I thought it was an orange color
knowledge: The red colour of blood comes from protein hemoglobin, while ripe strawberries, red apples and reddish autumn leaves are colored by anthocyanins.
