"Red, when mingled with black and white, gives a hue, which becomes when the colors are burnt and a greater portion of black is added. Flame-color is a mixture of auburn and dun; dun of white and black; pale of white and auburn. White and light meeting, and falling upon a full black, become dark ; dark blue mingling with white becomes a light blue; the union of flame-color and black makes leek-. There is no difficulty in seeing how other colors are probably composed. But he who should attempt to test the truth of this in fact, would forget the difference of the human and divine nature. God only is able to compound and resolve substances; such experiments are impossible to man."
