The theory of colour is one of the most
important aspects of applied optics and yet very few of us are
fortunate enough to encounter it in highschool physics are even at
university. This website provides a brief description of colour
theory of light from light sources over object interaction to the
human eye and finally visual perception.
The first three sections on arts, physics and
psychophysics describe the three general aspects of the theory.
Under demonstration you can find the outline for a demo that can be
easily constructed and show in grade 11 or 12 science classes. The
apparatus is easy to build and requires only a modest investment of
time and money. At the same time the apparatus allows for the
demonstration of quite counter-intuitive aspects of colour mixing as
well as other phenomena of coloured light.
A powerpoint presentation accompanying this
demonstration can be found in the presentation section. I have
included some remarks on timing of the presentation but of course
everything on this website is merely a brief suggestion to get your
If you have any questions with respect to the demonstration,
theory or any other general aspects of optics please do not
