What is grayscale coloring? Grayscale coloring means that you will be coloring over a black-and-white picture. The magic of coloring over grayscale is that the shading is already done for you! Even beginners with no knowledge of shading can achieve beautiful results. Colored pencils work beautifully with the grayscale images giving the finished picture depth and dimension. The paper is well suited for colored pencils but does not work as well with markers. If you use markers put a sheet of paper under the page in case of bleed-through. Features: 48 grayscale coloring pages. 8.5" X 11" white paper. Printed on one side only. A place for the colorists name and date on the back of each coloring page.
