Just wanted to point out some animations mistakes from Haruchika that probably few people noticed. In Rubik’s Cubes, there is a concept of color schemes, which is the orientation of the color that appear on each side of the cube. There are two major color schemes in existence.
The more common Western color scheme features white opposite of yellow, green opposite of blue, and red opposite of orange. It’s the one that we’re probably most used to seeing.
The second color scheme is the Japanese color scheme, which instead features blue opposite of white and yellow opposite of green (keeping red opposite of orange). I rarely see this scheme, but I notice it easily because of how different it is from the Western colors.
Now let’s look at the scene with Haruta solving the Rubik’s Cube. If you look closely at this screenshot, you will see a piece towards the left near Haruta’s left hand that has green and yellow on it. In the Japanese scheme, this is impossible because green and yellow are opposite of each other. As a result, we can conclude that Haruta is solving a Rubik’s Cube with the Western coloring.
Here’s another clue that this a Western cube. Notice the corner piece in the front that is blue, white, and orange. Since blue is opposite of white, this is also an impossible piece in the Japanese coloring. But here’s where things go wrong.
Look closely at the cube as Haruta puts it on the table (you may need to open the full-resolution image). Facing us is a yellow side, but the top is white. In the Western coloring, white and yellow are opposites, so they shouldn’t be showing up next to each other. This makes no sense!
The same mistake is made at the very end of the episode too when Haruta paints the cube.
Notice the orientation of the cube here. You can clearly see yellow on top with red in the front and blue on the right.
If you look really closely here, you can see the tinge of green on the bottom (it’s too dark to be white). This is the Japanese color scheme, right?
But here we have yellow and green magically next to each other…so, is this the Western color scheme?
Again, these are things that probably only someone who has solved Rubik’s Cubes as much as I have would notice, but I hope you found it interesting.
