Four Color Cube

The Four Color Cube only features stickers in four different colors. In the initial state the colors are arranged in such a way that no two adjacent stickers share the same color. This sticker arrangement follows the 'four color theorem', also known as 'four color map theorem'. In mathematics it states that, no more than four colors are required to color the regions of a map, so that no two adjacent regions have the same color.
