Systems and methods for correlating color correction instruction between two color correcting devices are disclosed. The method includes performing a nulling test on a representation a first device has of a known standard and retaining the results of the test. A second color correcting device performs a nulling test on the same known standard and the results of this test are retained. From the results of these two tests a color correction instruction of one of the devices may be converted to a color correction instruction on the other device so that substantially the same color correction effect is achieved.
