If you look through a prism in daylight the most wonderful colours can be seen: red, orange, yellow, green, blue, indigo, violet.

Smaller dark objects in the surrounding area appear to be totally colourful, lines look as if they are curved and, in the boundary between sunlit and shadowed areas, coloured fringes appear. Because the light does not pass through the prism in a straight line it is possible to transpose the image of the dark surface by turning the prism. The brightness of the light and the shadows of dark are seen as the source of all colour appearances.
