Colourblocks World is an educational app developed by Blue Zoo for Android devices. This free game helps kids learn about colors in a fun and exciting way. The app is based on the CBeebies and Colourblocks show, which follows a group of friends who use coloring-in magic and color mixing magic to bring Colourland to life.

The app is designed to introduce children to colors in a specific order, helping them connect the concept of individual colors with how they might feature in the real world. Children can meet each Colourblock as they are shown on CBeebies and Colourblocks on YouTube, discover some of their favorite things, and use color magic to color them in. The app also includes video rewards from the show's episodes.

Colourblocks World is COPPA and GDPR-K compliant and 100% ad-free, making it safe for kids to use. Blue Zoo, the developer of the app, is known for creating award-winning shows, such as Alphablocks and Numberblocks. Overall, Colourblocks World is a great tool for parents who want to teach their kids about colors in an engaging and interactive way.
