A third zone “Color Our World” features color shadows and a magic paintbrush. With the magic paintbrush, you choose the color palette you want and create a scene on a digital screen. Depending on the color, the scene and storyline change.
Even when you leave Colortopia you still get to play with the color palettes with a Colortopia mobile app. You can collect colors from each pavilion in Epcot and add them to your personal color palette to take home. The app also features exciting games to test your memory and understanding of color.
There are always fun things to experience at Disney, learning is an extra benefit.
