Color prediction and color matching methods and apparatuses with improved accuracy

A computer-implemented method for providing a correction term for a color prediction model, said correction term being associated with an adjusted sample coating being present under at least two different physical conditions, said method comprising:

• receiving by at least one processor via a communication interface a request to provide
• a color difference (CD1) between the measured color data of the adjusted sample coating being present under a first physical condition and the predicted color data of the adjusted sample coating being present under the first physical condition,
• a color difference (CD2) between the measured color data of a sample coating being present under the second physical condition and the measured color data of the sample coating being present under the first physical condition, said sample coating being associated with the adjusted sample coating, and
• a color difference (CD3) between the predicted color data of the adjusted sample coating being present under the second physical condition and the predicted color data of the adjusted sample coating being present under the first physical condition;
• and
• in response to the received request, determining with the at least one processor the correction term for the color prediction model using the provided color differences (CD1) to (CD3);
• and
• providing the determined correction term for the color prediction model via a communication interface.
