Strong Effects of Lighting
To enhance in particular, the color of the wood and the brick, Frank Lloyd Wright specified pink light bulbs in most of the light fixtures. These provide for a soft pink glow on the wood and the brick and thus simulates more closely the effect of natural light.
Another innovative artificial lighting effect was the specification of an infra-red lamp hidden in the hood of the fireplace. This, first of all, even without a fire draws the focus of the living room to the hearth which Mr. Wright considered to be the heart of his homes.
With a fire in the fireplace, this particular wave-length of light makes the fire appear more intense and the light reflecting off of the smoke particles creates a spectacular appearance in the smoke not normally seen.
Furthermore, the red light projects shadows of the especially designed fireplace grate onto the buff-colored fire brick below. The production of unusual shadows from both natural and artificial light was one of Mr. Wright's objectives in his designs strikingly enhancing the architectural effects.
