Document Type and Number:
WIPO Patent Application WO/2018/171815
Kind Code:
A1
Abstract:
A method for rapid mixing of any color. If three colors are to be mixed, the illuminance ratio of the three colors is adjusted as 1: Cr2: Cr3 so as to realize the color mix of the target color. If four colors are to be mixed, it is first necessary to determine the brightness proportion of one color, then, by calculation, the target colors (x, y) of the other three colors are obtained, then calculation by means of a formula delivers the proportions of the other three colors; alternatively, the brightness proportions of any two of the colors are determined, then the color obtained by mixing said any two colors according to brightness proportion is regarded as a first color, which is then mixed with the other two colors, the mixture and the proportions being calculated. If five colors are to be mixed, it is first necessary to determine the brightness proportions of three of the colors, then the color obtained by mixing said any three colors according to brightness proportion is regarded as a first color, which is then mixed with the other two colors, the mixture and the proportions being calculated. When the target color is known, the proportions of the colors to be mixed can be swiftly obtained through calculation.
