For example. Use a hard edge brush to draw the inks of a bed, making sure that the bed outline has no breaks, then use the magic wand to select the area outside of the bed. Invert your selection and contract it by 1 pixel. You should have a selected area that traces the shape of the bed but is just a smidge smaller. You can then fill this area on a separate color layer below your ink layer. Lock the transparency on your color layer and you can modify it with brushes and not worry about staying within the lines. You can also create alpha channels from the shape to mask off additional layers for shading or highlights. The idea is that you should be able to modify the colors without damaging the inks.
that is a very similar technique to what comic book colorists use. You create a layer for the inks, a layer for the flats (flat colors) a layer for shadows, a layer for highlights, and a layer for effects. Works pretty well
