The camera in a tablet or phone is powerful enough to render high-resolution images of interior space, and this app uses that capability to pick wall colors. Starting with a photo of the room, TapPainter draws from brand-name paint color inventories to find potential shades, then applies the new coats. Available only for iOS, $2.99.
What sets this app apart from the dozens of others like it is the complex algorithm that detects the edges of walls and differentiates shadows from true paint colors.
TapPainter also takes the wall’s current paint color into account when rendering what the new shade will look like.
When you find a color scheme that resonates, the app will find brand-specific color codes that you can bring to the hardware store. Currently, it only works on interior spaces.
