Description
This programme is highly integrated with the text or Units 10 and 11. It is presented by the author, Dr. Geoffrey Wexler who introduces a number of demonstrations (many for the first time on televi...sion) designed to question naive assumptions or instinctive explanations for colour effects. All of the demonstrations were recorded using television cameras on location. An industrial lighting laboratory shows the effect of different white lights used as illuminants in a domestic environment. The Colour Scientist Dr. Arthur Tarrant shows how an arbitrary colour can be matched using a particular combination of three coloured lights. A Research Scientist, Dr. Jim Bowmaker, demonstrates the response of three colour receptors of the eye. Complex and not-yet-understood colour contrast effects are shown (e.g. Lande). Finally, a brain scientist, Dr. Semir Zeki, points out the overriding control and influence of the brain (visual cortex) on colour perception regardless what is physically happening to the lighting of a scene.
