When you use "rearColor" and hold it over the designated coloring book mount, the coloring book becomes a three-dimensional 3D model that pops out from the paper. A sense of familiarity is created by reflecting the colors of the coloring book that you have painted. Even more amazingly, when you tap the screen, the coloring book pops out into a real scene, moves freely in a 360° panoramic view, and begins to move in a special world. (*Actions change depending on the coloring book content)
You can also take and save photos while playing the content, and easily share and enjoy them with your friends on SNS.
To enjoy coloring with rearColor, 1) install the app, 2) download the coloring paper, and 3) hold the app over the colored paper. This is how it goes.
