I am following color_correction tutorials as answered here , my issue is how to define custom colorchecker card instead of using cv2.ccm.COLORCHECKER_Macbeth used in model = cv2.ccm_ColorCorrectionModel(src, cv2.ccm.COLORCHECKER_Macbeth)in python. for example to take refernces of colorchecker cards from another image.
These are the reference color values
