Universal color code for AC wiring

Proposal for a universal color code for AC wiring. This is based on pure logic and thinking about human intuition.

Neutral means no voltage. Zero potential. Nothing. It should be black (no light).

With DC circuits the standard is to use red for the positive terminal and black for the negative one. The negative is usually considered to be the common wire, which is exactly the same as the neutral, but for DC, so it should be black.

The ground cable should be a color similar to that of the ground (or the soil). Brown. It's the only cable that can be without insulation, so in those cases, the bare copper will look brown. The insulation should be of the same color as the bare wire: brown. Otherwise there will be 2 possible colors for the ground cable. A mess.

Since it's commonly green or green with yellow stripes, and it's also the only cable with colored stripes, I would consider brown with green stripes (Like soil with grass...), but that seems useless.

Anyway: brown with or without green stripes for ground.

The 3 phases should be represented with the 3 main colors we use to represent all the other colors in real life. Red, Green, and Blue. The colors of the pixels. It nicely maps the corresponding phasor of the voltage of each line. This way the neutral and ground cables are clearly different from the live ones (They aren't in the color wheel. They aren't completely saturated. They are greyish)

For a 6 phase network, just choose the colors in between. Since we have used greyish (non-saturated) colors for the other connections, all of the intermediate phases's colors are free to use. It would be: Red, Yellow, Green, Cyan, Blue, and Magenta. From this 6 phase network you could extract two 3 phase ones: Red, Green, Blue and Yellow, Cyan, Magenta. This would work for an indefinite amount of phases.

I don't understand why every country has to have a different color code. Let's end this mess.
