Create colorful adventure scenes that pop! There are 30 pages of color-coded illustrations to fill in with markers. Use the included 3-D glasses to transform the colored pages into multi-dimensional looking scenes -- warm colors like red and orange come forward, while cool colors like blue and green recede into the background! A terrific activity for artists ages 4 and older, the unique coloring and viewing experience promotes fine motor skills, color recognition, and creative play.Age 4 to 6 years
