Abstract
A method for measuring a color value such as brightness or intensity of a sample which comprises: measuring color values for a plurality of color standards using a reference color measurement device to obtain a matrix Y that contains the measurements of the color standards as measured by the reference color measurement device; measuring the same plurality of color standards with a field color measurement device to obtain a matrix X that contains the measurements of the color standards as measured by the field color measurement device; calculating a color correction matrix B based upon the equation Y=BX, measuring the color value for the sample with the field color measurement device, and applying the color correction matrix B to the reading of the sample color to obtain a sample color value that approximates that sample color value that would be obtained using the reference measurement device.
