The upper left A quadrant typifies logical processing, and therefore, the colour chosen to represent this quadrant is cerulean blue—clear and to the point. The lower left B quadrant—the structured and organised quadrant—was designated as green because green suggested groundedness. With its emotional, feeling and interpersonal orientation, the lower right C quadrant was assigned red because of the emotional passion implied by the colour. The upper right D quadrant, with its imaginative qualities, was assigned yellow because of that colour’s vibrancy.
