When the color of projected light is important, filters can be designed to correct the color temperature. This is either done with a flat filter placed in front of the light source (managing what wavelengths are transmitted) or a filter deposited on the surface of a reflector (managing what wavelengths are reflected).
Typical lighting applications include display, photographic, theatrical, and medical. The design of a color correction filter depends on the light source being corrected. Color correction filters/reflectors are highly customized to achieve the desired performance.
