## Colour Anchoring

Anchor the colour palette explicitly when generating multiple images:

```
Colour palette: warm terracotta (#C66A52), cream, natural wood.
Background should include terracotta-toned elements to maintain
brand consistency across all images.
```

List 3-4 specific colours or materials. The model picks these up more reliably than abstract terms like "warm tones".
