Designed for children aged 5–12 years old, Chromville consists of Android and iOS apps, along with a series of coloring template pages which can be downloaded and printed off ready for kids to color in. The pages tell the story of a distant world where color is fading away and environment-based characters are losing their power, and only you can save them by coloring them in.
Once youngsters have finished each of their artistic masterpieces, the Chromville app can be used to scan them with a smartphone or tablet. The app then recognizes the coloring pages, and brings them to virtual life on the screen, complete with 3D animations incorporating the children's designs into the story.
As the chapters progress, there are a series of on-screen mini-games which form part of the narrative, and also feature the characters as colored by the user. This is similar to the way in which Lego Fusion incorporates a user's physical construction, and is what sets Chromville apart from other augmented reality coloring apps like ColAR.
