Abstract: A projection system and method therefore related to a first projection device; a second projection device; at least one spatial modulator; and an electronic processor configured to: receive a two-dimensional video data, generate a first plurality of intensity values of a first color gamut and a second plurality of intensity values of a second color gamut, subtract a luminance threshold from a plurality of pixel values of the second color gamut to yield a plurality of positive pixel values and a plurality of negative pixel values, set respective ones of the plurality of pixel values to predetermined values to obtain a residual of the second color gamut, add the residual to the first color gamut, add maximized pixel values to the first color gamut and the second color gamut to create an output gamut, and blend the output gamut with a native color gamut to generate a blended gamut.
