British politician and orator William Gladstone (1809-1898) studied The Iliad and The Odyssey by the Greek writer Homer who was active during the eighth century BC, and came to the conclusion that Homer must have been colorblind. However more recently, scholars have come to believe that color perception must be evolving and that perhaps, the world saw in black and white until a human consciousness reached for the perception of additional colors over many generations; that our ancestors could see first black and white, followed by red, yellow, green and then blue.

My friend Ella turned me on to this program by Radio Lab…

Radio Lab: Why Isn’t the Sky Blue? Radiolab is a show about curiosity. Where sound illuminates ideas, and the boundaries blur between science, philosophy, and human experience.

The program asserted that colors entered the human consciousness as they were manufactured, and the earliest manufactured blue pigment was created in ancient Egypt.
