However, it's crucial to remember that you should never rely solely on color to identify wires. Here's why:

* Color codes have changed over time: The color codes for live, neutral, and earth wires have changed over the years. What was standard decades ago might be different today.

* Mistakes happen: Wiring can be mislabeled, especially in older homes.

* Safety: It's dangerous to assume you know which wire is live without testing it properly.

Always use a voltage tester to verify which wire is live before working with any electrical system. This is crucial for safety and to avoid accidental electric shock.

If you're unsure about any wiring, consult with a qualified electrician. They have the expertise to identify wires correctly and ensure your safety.
