The part absorbed, or which does; niit appear, is the com-/ plementary of the colorseen. This m ay be madeperfectly clear by thecircular diagram. If wejook, for example, upon a red surface supposed to be presented inFig. 38, yellow and blue are seen to be the colors necessary to com-plete it to white; they are therefore the complement of red ; butyellow and blue form green, as shown in Fig. 89, which is thereforethe true complement of red, that which it lacks to make white. If weVook upon a yellow surface (Fig. 40), blue and red are deficient; blue. A. NEW SYSTEM OF ARRANGING THEM. 91 Fig. 4-2.
