Haunted features 25 creepy grayscale images for you to color using your favorite dry mediums such as pastels or colored pencils. *Some of the images in this book have been intentionally left darker to maintain the Goth inspired aesthetic of the artwork. Grayscale coloring is a relatively new style of coloring that uses a photograph or artwork's natural shading to enhance the depth of the colorist's finished page much like the difference with vintage films and photographs and those that have been "tinted" or colorized.
