"Since pictures such as mine are so different from the pictures people are used to framing, it isn’t really strange that they should require different treatment. White not being a color (as is gold) forms the best frames for pictures high in key and in pure color, as it does not destroy the balance of color in the picture and brings out each color in its fuller intensity. Black is next best, I think."
