1. An illumination system for use in a display system, comprising:
- a light source producing light;
a color wheel, further comprising;
a set of primary color segments producing primary colors of red, green, and blue; and
a color rendering segment, wherein the color rendering segment has a color that is determined based upon a product function that is proportional to a product of the luminance sensitivity of a viewer'"'"'s eyes, a spectrum of the light from the light source and a predetermined wavelength threshold of the product function.
