You may or may not already be familiar with grayscale or greyscale coloring. It is a coloring technique that uses the existing shading in a grayscale image to create more realistic, three-dimensional, and lifelike works of art. When coloring, you color directly over a grayscale photo, as opposed to line art coloring, where you color the white spaces between the lines. It is a perfect way for both beginning colorists and more advanced artists to create truly stunning coloring pieces. Grayscale coloring for adults is one of the newest and most exciting trends in adult coloring and is gaining popularity fast, and with good reason. People are drawn to grayscale coloring because it is fun! It also results in very realistic pictures that can rival gallery-quality art. Grayscale images are created from specially selected photographs, paintings, and drawings. They are then converted to images for coloring using specialized graphic design software and hand-tuned to create the perfect shading and highlights for coloring.Halloween coloring book contains witches, pumpkins, skeletons, and more.
