A multi-mode color filter 400 having an inner hub region 402 used to mount the color filter 400 to a motor shaft. A first track 404 and a second track 406 of color filter segments arc formed on the color filter, as is an optional clear track 406. The first and second tracks each have a different set of color filters. One set of filters is chosen to improve image brightness, another set is selected to improve color saturation. Typically, the set of filters used to improve brightness includes one or more clear segments, while the set of filters selected to improve color saturation does not. Depending on the image being projected, the user or the display controller moves the color wheel to select a particular filter set.
