Lighting choices can affect how we perceive spaces, even the colors of objects and surfaces. As a result, lamp color characteristics are a critical factor in a wide range of spaces, from high-end retail, where merchandise must be presented as vibrant and in its true colors, to offices, where good lighting renders faces naturally and facilitates interaction. Although almost all architectural lighting uses white light, white is available in many hues and color rendering abilities, providing a palette of choices for lighting spaces.
