Shading(see LightSource)
shading is meant to show volume and give the viewer an idea of the shape of an object. every bump on a surface will cast a shadow on the oposite side from where the lightsource comes from. stronger lightsources, stronger shadows. more lightsources, less shadows.
also the material where the light is casted will affect how highlights will be prduced.
a basic way to determine wich color should be used for a shadow is to directly reduce the luminosity of a color, but there are plenty ways to shade, either by contrast, by hueshift, by adjusting the Saturation, or even by dithering. in any case, only practice and experience determines what would be the best choice, as there is no fixed rule of what can or cannot be used as a shade.
