I was doing some research on colour and came across this extremely enlightening lecture by Professor Pete Vukusic from the University of Exeter. In this lecture he explains the colour spectrum, how our eyes see light, infra-red light, colour blindness, mixing pigments, interference, iridescence, photonic makeup, neo-impressionalism, pointillism, just to name a few. This lecture definitely opened my eyes to light and colour and how complicated the workings of each really are. Definitely worth the hour to view this video.
