Theory and experiment of a new white-light image processing technique for black-and-white image addition and "subtraction" by means of Fourier plane spatial color filtering are described. The intensity transmittances of three (or two) processed images can be expressed in a chromaticity coordinate system of primary colors and so are the results of the addition and/or "subtraction" of the two images.
