If a predefined color chart is not suitable, you can use your own custom color chart as a calibration reference. In Color Calibrator dialog select the Reference Chart type as "Custom" then click on "Edit Chart"

Edit Custom Reference Chart

You will need to provide chart layout, number of rows and number of columns, and the CIE L*a*b* color reference values for each chip in the chart. The color reference values are loaded from a CVS (comma delimited) text file. The file is required to have 4 columns with headings: SAMPLE_NAME, LAB_L, LAB_A, and LAB_B. Order of the columns is not important. Any other columns beside the 4 mentioned will be ignored. Here is example of the first 3 rows of such file:

SAMPLE_NAME, LAB_L,  LAB_A,   LAB_B
Dark Skin,  38.960, 12.130,  13.840
Light Skin, 65.500, 15.590,  16.810
Blue Sky,   50.690, -2.090, -21.750

Note: you can further customize the chart by selecting which chips ere enabled for computing calibration mapping.
