It is a curious fact that by the mixture of any two prismatic colors which are represented in the chromatic circle on Plate 32, the result will always be a color which lies between the two colors used. If the two colors are about equal in strength then the resulting color will be found about half way between the two; for example, by the mixture of the prismatic red and yellow we get orange, the same as in the mixture of pigments; so it is with red and blue, which produces violet; yellow and blue, which produces green. But by the mixture of the prismatic red and green we get yellow; while the mixture of red and green pigments produces brown. And by the mixture of the prismatic green and violet we get blue; while the mixture of green and violet pigments produces an olive. Also by the mixture of the prismatic orange and purple we get red; while the mixture of orange and purple pigments produces a russet.

By the mixture of prismatic colors which are complementary the result will always be white; and by the mixture of prismatic colors which are nearly complementary the resulting tint will always be nearly white. It follows then, that in the mixture of two pris-
