The interference colors are the result of destructive interference, and hence, subtraction of primary colors from white light.

Work Step by Step

As seen in Figure 27.8, the radiation curve of sunlight can be divided into three regions: red, green, and blue. These are the additive primary colors. When light of one of these colors interferes destructively with itself, that color is subtracted from the white light. The result is one of the complementary colors: cyan, magenta, and yellow. This is discussed on pages 553-554.
