you gonna use and editor that work with layers,

Have to the parts that are shadow, that also works for lighting, differently be in different layers

You gonna close the layer that you want to coloured at the moment, and paint the shadow in the layer that the draw will be shadowed if you don't close that padlock the paint will be transferred for other layers that are under the painted layer.
