These scenes of animals, flowers, and landscapes are gorgeous in daylight and at nighttime. As you color in the pages, use the included glow-in-the-dark pen to highlight features such as eyes and patterns, or to add an outline. Glow in the Dark Coloring also provides instructions on coloring techniques, how to apply the glow details, and fascinating facts about bioluminescent creatures. Each of the twenty detailed illustrations in this book features a dark background, giving the finished scenes a wonderful nighttime look.
