Thanqol, as an exercise since I don't have the tools; try to go through the provided charts and see if there is a mathematical correlation. If shadows are generally always [x] RGB spaces darker, then we can work out correlations. It becomes easier when shading is "shadowy afternoon; use a color 20 degrees cooler" rather than "green; use a third stage viridian blue" y'know?
