In your colored drawings, try using darker shades of the same color(s) of the object itself instead of using black to create the shadows. The same goes for the surface on which the object is set (note: the object's color may also be reflected onto the surface). For example in the real world, if you look at leaves in sunlight you'll see the leaves in the shade are actually a darker green and they are a very light green where the sun is reflecting.
