Final Stage: Darks

The final pass in this watercolor sketch was to hit the pendant light with a dark wash to separate it from the background.  I made a very dark wash and applied it to the bottom and left side of the light  to reinforce the direction of light and shade.
When it was still wet I dipped my brush directly in ultramarine blue and hit the left side of the base of the light...adding a very deep tone.

The contrast in value is what will create spatial depth in a fairly flat drawing.
