Purpose: Demonstrate how negative filters combine to give color combinations
Description: Place two negative filters on the overhead projector as seen in the top row of photographs below, so that their colors can be viewed. When they are overlapped, as seen in the lower row of photographs, negative color mixing can be observed. Each negative color slide removes one of the primary colors - its complementary color - from the light. Two series negative filters remove two of the primary colors, leaving the third as the resultant color.
