Very great BUT....

Color is a great coloring app you can get pile of different content. I love the variety of the kinds of photos. If you want a nice quit and easy pass time I really recommend this app.
The only problem I have with the app are the don’t get me wrong amazing 3-D pictures. I new feature where you can color three dimensional images, in the app you cannot turn the image in many directions and when you zoom it will on zoom on a specific part. In the end the more detailed images in 3D become instantly become harder to finish. And I know many people like a challenge but if you use this app for a relax time I would suggest staying away from the three dimensional images. But that is only my opinion if you want to use that feature go ahead it is a good and interesting part of the Color experience.
