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. When coloring this way you will get the look of shading without having to shade at all - providing the depth which is so hard to achieve on a traditional coloring page. greyscale coloring books for adults.greyscale adult coloring.grayscale coloring books for adults.grayscale coloring book.valentine coloring book.valentines day coloring books for adults.
