Upon completion of a drawing, I consider whether a picture's appeal will be enhanced by color or if the adding color will become a negative distraction. I've ruined many good drawings by coloring them in the past. Now I scan the piece before I add color this way I can create prints, if nothing else, out of the black and white drawing should I be unhappy with the painted version.
Adding color can really bring a piece to life. The colors I choose often reflect the mood I'm in. For this reason I often give it a day before painting.
Above is an example, before and after, of one of my drawings. I don't always draw out my pieces first--only if I think I'll like it more as a black and white piece. More often I outline and detail after I paint.
