A simple Palette Generator that generates random 3 colours with just one click. Each time you click the button, a random colour is generated, and you can lock any colour to keep it unchanged while others change.

Features:

1. Generates a random colour palette.
2. Lock/Unlock a specific colour to prevent changing.
3. Copy codes easily.

How It Works:

1. Click the Generate Colours button.
2. Each box gets assigned a random colour.
3. Click the lock button on any box to freeze its colour.
4. Generate again — locked boxes stay the same, others change.
