In a color reproduction method for reproducing a color image on a color monitor screen by processing primary color signals of cyan, magenta, yellow and black which are derived by scanning color separation films of cyan, magenta, yellow and black, respectively, on the basis of the Neugebauer equations, at first the primary color signals of cyan, magenta and yellow are processed in accordance with specially derived color reproduction equations representing halftone of three additive primary colors of red, green and blue to produce three secondary color signals and a tertiary color signal, and then amplitudes of a paper color signal, the primary color signals, the secondary color signals, the tertiary color signal and the primary color signal of black are adjusted in this order independently from each other. An apparatus for carrying out the above color reproduction method comprises seven multipliers, four inverters and twenty seven variable resistors and by suitably adjusting the variable resistors the colors of the image displayed on the color monitor can be controlled.
