What are the modern UK wiring color codes for live neutral and earth?

Explanation:
In modern UK wiring, live is brown, neutral is blue, and earth is green/yellow. This is the current standard used in new installations and aligns with European color coding for safety and clarity. The option that uses brown for live, blue for neutral, and green/yellow for earth matches this standard, so it’s the best choice. If you encounter red or black in new wiring, that indicates older wiring that predates the change; the earth should still be green/yellow in new work. For three-phase circuits, the live conductors are brown, black, and grey, with earth remaining green/yellow.
