A two-panel projection display system includes a color wheel having color filter segments that transmit light having a secondary color, namely cyan, magenta, and yellow, made up of two primary colors. A primary color separator, such as a second color wheel, a transflective dichroic beamsplitter, or a color-sensitive polarizing switch separates the secondary color beam into a first polarized primary color beam and a second polarized primary color beam, which are directed to first and second imager panels. A beam combiner combines the first polarized primary color beam from the first imager and the second polarized primary color beam from the second imager to form a projection beam. Accordingly, any two primary colors can be imaged at the same time enabling the system to be white point balanced.
