This paper proposes a color conversion method for a multi-primary display to reduce falsecontours. Wide gamut display is realized by using multi-primary display. The display excelscurrent displays in color reproduction. There is flexibility in the combination of primary colorsto reproduce a target color in a multi-primary display. If similar colors are converted bydifferent combinations of primaries, false contours may be reproduced in the areas wherecolors are smoothly changed. The problem of false contours can be reduced by devising aconversion method. We propose color conversion method that reduces false contours by usingmathematical programming. The color signals were obtained by SUMT and Newton's method.As a result, false contours have been reduced with a small color difference.
