Summary:A method for mixed color correction is provided. Based on the variations of the chromaticity coordinates required for adjusting between the target color and the actually-measured color, variations of illuminances of one or two of RGB of the three colors are calculated for adjusting the actually-measured color to achieve the variations of the chromaticity coordinates required for adjusting according to the correlation between the chromaticity coordinates and the tristimulus values, until the required variations of chromaticity coordinate are within a required range. This method can quickly and accurately correct and adjust the actually-measured color, guarantee the consistency of lamp colors, and is convenient for application.
