ABSTRACT
Color is one of only two design elements that have an unconscious response from the viewer's brain. The other is texture. The viewer will respond to the color used before they can read a label or make sense of the imagery. This is the power of color. Without light, there would be no vision or color, because light and color are inseparable. Light is considered visible energy. To make matters more complex, as the amount of light varies (increasing or decreasing), so does the amount of color. Sir Isaac Newton was one of the first to understand what people now consider their modern concept of the relationship of light and color. His experiments in the seventeenth century using a prism demonstrated that white light contained or was composed of the visible colors of the spectrum. Since there are so many different types of lamps and light sources, understanding their effect on color perception is essential.
