A method for adjusting color measures tristimulus values of white, red, green, and blue at all grayscales performed on a LCD panel, and then converts a white-measured stimulus set (WX255, WY255, WZ255) of measured stimulus sets (WXp, WYp, WZp) into a target luminance value WYp, a target chromatic values WXp, WYp of each grayscale, and subsequently converts the target luminance value WYp, the target chromatic values WXp, WYp into target stimulus sets, and finally calculates a set of ratios performing as white at each grayscale on basis of each target stimulus set (WX'p, WY'p, WZ'p) and sets of tristimulus values at all grayscales. Accordingly, the corresponding ratios of three primary colors performing as white at each grayscale are calculated based on the target luminance value WYp, target chromatic values WXp and WYp. As a result, the calculated RGB ratios are more precise.
