rearColor is an Android app developed by Remodelpartners Inc. that allows users to turn their coloring pages into 3D models. Simply scan the colored page with the app and watch as the image comes to life in the real world. The app reflects the colors used in the coloring page, creating a sense of familiarity. Moreover, users can tap the screen to see the image come to life in a 360-degree space or special world, depending on the content.

Users can take photos and save them while playing with the contents, making it easy to share with friends on social media. To enjoy coloring with rearColor, users need to download the app, download the coloring pages, and scan the colored pages with the app. However, the app is currently experiencing issues with Android 8.0 and above. The developers are aware of the issue and are working on an update to fix it.
