Gunze Sangyo CS582 Mr Color Dark Yellow Color Modulation Paint Set

The actual figure will look three dimensional because of the shading as light falls on it, but if nothing is done after painting, the figure can give a sort of flat impression, has little presence and becomes dreary. The technique used to emphasize the stereoscopic effect by changing the tone of even just one color is called "Color Modulation". In some cases where you have a small piece such as a model, it is not easy to see the change just by changing the color of each surface. So gradation painting is used to emphasize the stereoscopic effect.
