George French, Printing in Relation to Graphic Art
“ It appears that those complementary color schemes which can be perfectly justified are such as reflect light rays nearest like the rays that show us white. Red and58 green, the two most pronounced and vigorous colors, are complementary. When mixed in the proper proportions they produce white, but this does not mean that they weaken each other when otherwise used; when placed side by side they enhance each other's power and brilliancy by reflection. ”
