Your room, not a generic template
The fundamental advantage of using a photo of your own room is that you see the new wall color in context: with your existing furniture, in your actual lighting, next to your floors and trim. A color that looks perfect in a staged stock room photo can look completely different in your space with its unique characteristics.
Take a photo that includes as much of the room as possible — the more context visible, the more useful the preview. Daytime photos with natural light produce the most realistic previews.
Applying the color to wall surfaces
Tap any wall surface in the photo to select it. The AI detects the wall boundaries — separating wall from trim, ceiling, furniture, and windows — and applies the chosen color only to the wall pixels. The result respects the room's existing light and shadow map, so recessed areas look darker and well-lit areas look lighter just as they would with real paint.
For rooms with complex wall geometry — alcoves, returns, angled ceilings — tap each surface area separately to apply color to each section.
Understanding how lighting affects the preview
The same paint color can look meaningfully different under morning north light, afternoon south light, and evening incandescent light. The preview reflects the lighting in your specific photo — which means taking multiple photos at different times of day and previewing in each gives you a more complete picture of how the color will actually live in the room.
The app doesn't simulate different lighting conditions — it uses the lighting in your photo — so for critical decisions, photographing the room in multiple lighting scenarios is worthwhile.
Going from preview to purchase
Once you've found a color you're confident about, the app shows the full product details: brand name, official color name, product code, and finish options. Copy the product code and take it to any store that carries the brand to have it mixed.
For particularly high-commitment decisions (large rooms, expensive paint), ordering a 4-ounce sample can and painting a 12×12-inch test patch is still the gold standard confirmation step — but the virtual preview dramatically narrows the candidates from a dozen options to one or two.
