In fact, the Rubik's Cube does not have only one color scheme, and now the original version is out of fashion. The original color scheme of the Rubik's Cube is the current Japanese scheme. The current color scheme is to arrange a pair of colors with similar color systems on opposite sides, while Japan maintains the original color scheme. In fact, there are many other color schemes.

Rubik's cube lamp appearance:

Rubik's cube six stickers are usually composed of six colors: red, yellow, blue, green, white and orange. There will be differences in printing methods in different periods and places, but they are basically red on the front, orange on the back, yellow on the top, white on the bottom, Zuo Lan and right green.

Without these restrictions, there are 30 ways to paste Rubik's Cube stickers. Because of the symmetry of the Rubik's cube, we might as well specify blue as the top surface when pasting.

There are five kinds of stickers on the reverse side, and the remaining four sides form a ring. The four colors of this ring are removed from the rotation, and the same situation has a 3×2 paste method. This is because, for this ring, we can also specify one of the four colors as the front, the back has three pasting methods, and the remaining two sides correspond to two pasting methods, so the Rubik's cube sticker has 5×3×2=30 pasting methods.
