 | | The colour of the sky, the sea and the rainbow are due to the physical effects of scattering, refraction and dispersion of light. |
 | | Colour is added to food to improve the appearance, delight the on-looker and deceive the senses. |
 | | Man has even associated his feelings with colour: browned off (fed up), red with anger, green with envy, yellow livered, pink with pride, pink of health, etc. Viewing brilliantly coloured objects for a prolonged period on TV or the computer screen causes considerable stress due to what is known as visual pollution. |
