THE CONTRAST OF COLORS. 9 



amined in succession, the last one will appear duller and inferior in 

 brilliancy to the others, but it will still appear red. 



Proceeding with the examination of the effects produced on the 

 other colors, we find that orange has been moved toward yellow, and 

 also toward the centre of the circle ; hence our diagram tells us that 

 red, when put into competition with orange, causes the latter to appear

more yellowish, and at the same time less intense. Advancing along 

 the circumference of the circle, our diagram informs us that yellow is 

 not much affected in the matter of saturation or intensity, but is simply 

 made to appear more greenish. The two circles during superposition 

 cut each other near the position of yellow ; from this point onward the 

 effect changes as far as intensity or saturation is concerned, the green- 

 ish-yellow being moved decidedly outside of the original circle as well 

 as toward the green; it is made, therefore, by contrast with red, to 

 appear more brilliant as well as more greenish. Green is made to 

 appear somewhat bluish and more brilliant. Greenish-blue has been 

 considered. Cyan-blue is made to appear slightly more greenish as well 

 as much more brilliant ; the same is true of blue, though its increase in 

 brilliancy by contrast with red is rather less than is the case with cyan- 

 blue. Violet has its hue considerably altered toward blue ; its satura- 

 tion is diminished. Purple is made to look more violet and is much 

 diminished in saturation. 



If we wish to study the effects produced on the colors of the chro- 

 matic circle by contrasting them with yellow, we have of course merely 

 to displace the upper circle along the line joining yellow and its com- 

 plement, ultramarine-blue, and then proceed as before. 



It is quite evident that this contrast-diagram will furnish correct 

 results only on condition that the colors in it are properly arranged ; ,if 

 the angular positions of the colors are laid down falsely, the results in 

 the matter of increase or diminution of brilliancv will also be false.
