Undercoat / room preview
See the color on your wall before it's on your wall.
Upload a photo of the room. We find the walls, you pick the paint, and Undercoat blends it in with real shadow and light — no more guessing from a 2-inch chip under store lighting.

Snap the room
One photo, any light. We don't need a perfect shot — just the wall you're deciding on.
Detect
We trace the walls
On-device segmentation finds each wall plane so paint stays inside the lines, around trim, switches, and shadow.

Drop in a color
Pick from any brand's palette or a custom hex, and compare two or three side by side before you decide.
