Red

Red is impossible not to notice; it is one of the most preferred and expressive colors. He attracted attention from ancient times: and because such are the properties of his nature and that of man; and because it is associated with such vital concepts as blood and fire. In ancient Rome, the color of blood symbolized courage, power and authority. Only emperors could afford such a color of clothing. The togings of the Roman senators were red. Cochineal was very expensive - an insect, from the carapace of which they extracted a waterproof coloring matter.
Why are there three red hands in this picture? I just love red, that's all.
