A system that illuminates water in a water display in broad daylight is described. The system may include a color filter that directs a desired color or range of colors onto the water. The source of light may be the sun or an artificial light source. Where the light source is the sun, a heliostat may be included to track the sun and reflect sunlight to the color filter. Other reflecting mirrors may be included to provide a line of sight between the light source and water display being illuminated.
