VINTAGE VALENTINES DAY coloring books for adults When coloring over greyscale try to think of it as a color by numbers for adults (Just without the numbers.) The darkness or lightness of the grey will be your guide and will show you how dark or light color you should use and exactly where on the image you should use it. Light colors over light grey areas, dark colors over dark grey areas, and the medium colors in between.
