The method includes obtaining reflectance and / or colorimetric data from a target coating using a processor, and using at least one Keplerian planet from the obtained reflectance and / or colorimetric data using the processor And calculating virtual color response data using one of an equation of motion law and at least one differentiation of at least one equation of Kepler's law of planetary motion. The method also includes using processor and hypothetical color response data to produce a coating pigment coloration that is identical in appearance to, or substantially similar to, the target coating.
