Colors and forms automatically suggest to us a thought or a feeling. The colors we wear and the colors that are around us have an effect upon us and produce an atmosphere. I once happened to go to a newly formed club, and some members said to me, "There is surely some evil spirit in this house, for since we have had our club here, every time we have had a committee meeting there has been a quarrel!" I directed their attention to the walls of the room where they used to have their meetings and which were covered with red paper. I said, "It is this red wallpaper; it appeals to the fiery side of your nature, and if there is any inclination to fight it encourages you.'
