Projection systems and methods therefore involve a first projection device; a second projection device; at least one spatial modulator; and an electronic processor configured to: receive 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 produce a plurality of positive pixel values and a plurality of negative pixel values, a corresponding pixel value of the plurality of pixel values is set to a predetermined value to obtain a residual of the second color gamut, the residual is added to the first color gamut, the maximized pixel value is added to the first color gamut and the second color gamut to create an output color gamut, and the output color gamut is mixed with the native color gamut to generate a mixed color gamut. 投影系统和方法因此涉及第一投影设备；第二投影设备；至少一个空间调制器；以及电子处理器，被配置为:接收二维视频数据，生成第一色域的第一多个强度值和第二色域的第二多个强度值，
