"There are no fine tones in watercolor unless one makes play with the white of the paper, not only letting it shine through transparently, but contriving to set it off in varying proportions around each brushstroke. This luminous intermediary intensifies each tone and harmonizes it with the others around it. If a patch of blue is put down beside a patch of red and the two are brought so close as to touch each other, their meeting will be discordant. If a white space is left between thes two hostile tones, they will harmonize, each shading off into the unpainted white, and their reciprocal intensity will be heightened by the contrast with this white surface. These interplays of white with colors are always ageeable to the eye. Indeed there are some tones that cannot keep their quality unless they are surrounded by white. Yellow and orange become meaningless, lifeless, if the eye cannot compare them with a neighboring white. Contrary to the rules, one must have no fear about leaving blank spaces."

"All great masters are chiefly distinguished by the power of adding a second, a third, and perhaps a fourth step in a continuous line. Many a man had taken the first step. With every additional step you enhance immensely the value of your first. "
