The film shows a post-apocalypse world where acid rain falls in ashes. A few survivors live underground, longing for the outside world. There are only a few healthy people among them who can go out into the real world. The survivors can only imagine what the outside world looks like. The main character Fuyu paints the outside world with his imagination and the colors that his friends deliver from the outside world. Is the world really that color? Like the title, the color of the world is what makes it all together. It doesn’t matter if it’s real or if it’s just an ideal dream. Will Cocolors be another promising star in the Japanese animation industry? (NAH Ho-won)
