# Japanese vs Western Color Schemes

Did you know that there is more than one color alignment for Rubik’s cubes? The Japanese version of the cube has the same colors as the standard one, but with a different placement. The traditional cube’s colors are: white, yellow, orange, red, green, and blue. The Japanese version has the yellow and blue colors switched. In the case of Japanese cubes with a white plastic body, some have black stickers instead of white ones.

### WESTERN COLOR SCHEME

The Western color scheme is used in the majority of Rubik’s Cubes and other cube-shaped twisty puzzles. The most common way to solve cubes with this color scheme is to start with the white face and finish with the yellow one.

This color scheme is known as “BOY”: blue-orange-yellow. The Western color scheme is also referred to as “Minus Yellow”. The reason is that the scheme adds yellow to the face opposite each primary color face, as follows:

On the opposite face of white is yellow: white + yellow = yellow

On the opposite face of red is orange:  red + yellow = orange

On the opposite face of blue is green: blue + yellow = green

### JAPANESE COLOR SCHEME

The earliest mass-produced cubes used the Japanese color scheme. They are legal in official competitions by the WCA, and a few speedcubers still use them. Since the blue and yellow faces are switched, speedcubers prefer to start with a blue cross, rather than a white one, as mentioned earlier.

In case you are wondering how the WCA approves of any color scheme, here is a quote from rule 3a3: “Polyhedral puzzles must use a color scheme with one unique color per face in the solved state. Each puzzle variation must have moves, states, and solutions functionally identical to the original puzzle.”
