Abstract: A control interface for producing a composite color through the mixing of primary colors selected from a first color spectrum including red, yellow, and blue, resulting in the display of said composite color through a light array containing lights of a second primary color spectrum is disclosed. The user selects a color or colors from the first primary color spectrum, and a circuit and control algorithm controls the relative intensities of the colors comprising the second primary color spectrum, rendering the selected color or a mix of previously selected colors through the light array. Through the selection and graduated combination of the primary colors of the first spectrum, the creation of a wide range of colors in the visual spectrum is obtained for lighted color applications.
