Hex values are real Sherwin-Williams colors but will appear different under real lighting. Order real paint chips before committing.

Options

Rendering algorithm

Albedo-aware (default) Divides out the photo's baked-in shading, then multiplies by the target color. Dark→light swaps read as shaded light instead of muddy gray. Needs a per-surface albedo. Legacy luma tint Simple grayscale-times-target tint. Preserves the photo's original contrast exactly, but dark surfaces stay muddy when painted with light colors.

Mask editor

Click on the photo to add polygon points. Press Enter to close a polygon and assign it to the active surface. You can draw multiple polygons per surface (e.g. siding panels separated by the garage).

Click add point
Enter close polygon & save to active surface
Esc cancel current polygon
Backspace remove last point
Right-click a polygon to delete it
Scroll zoom · Space + drag to pan

Surface albedos

The real paint color of each surface, used to undo the photo's baked-in lighting so dark→light swaps read correctly. Auto-computed from the brightest diffuse pixels in each surface's masks (95th percentile, to skip specular outliers); use Sample to pick a specific pixel if auto looks off.
