Why Walnut Paint Looks Different in Person
Walnut paint colours are notoriously sensitive to lighting conditions and surface texture. A walnut that reads beautifully in a north-facing room can look completely different in direct afternoon sun — which is why paint swatch decisions made under shop lighting so often disappoint.
AI paint visualisation removes this uncertainty by applying the colour to a photo of your actual windows — under your real lighting conditions — before you commit to purchase.

| Sheen | Satin or semi-gloss matching trim |

| Durability | 8–12 interior; exterior sash 5–10 weather-side |
| DIY cost | $20–$60 per window |
