Palette: Shikisai no Shoujo

Synopsis

Animated graduation work by Hirota Hirata. There was no "color" in the boy's world. One day the boy finds an old palette in a closet. When the palette opened, a little girl with colored eyes appeared from inside. The things she touched were magically colored one after another, and the boy, fascinated by the "colors" reflected in the black and white world, ran after the girl. "Show me the color, you just have to do it again." (Source: Video description, translated)
