The room was large and faultless. A psychologist, hired from Cambridge, had planned the decorations – magenta and gamboge; colors which – it had been demonstrated by experiments on poultry and mice – conduce to a mood of dignified gaiety. Every day carpet, curtains and upholstery were inspected for signs of disrepair. A gentle whining note filled the apartment, emanating from a plant which was thought to “condition” the atmosphere.
