Imagine the beauty of a sunset, exquisite if not gorgeous colours of the rainbow, flamboyant views of autumn leaves and twinkling stars marching as they scream out their glitter. How quaint that the perception of colour causes us to deeply appreciate the beauty of nature. Although Men have been aware of colour since the ever dawn of the unknown, yet, its nature remained a mystery until only the seventeenth century. Thus, our understanding of colour adds greatly to our knowledge of the Universe.
