Guess I should have listened
Others had rated this with one star and said it didnt work but I was still curious (because it was mentioned on gizmodo). Unfortunately the others were correct and it doesnt work "as advertised".
Or perhaps it does work as advertised and Sprout! just forgot to mention a few steps. The very first screenshot (currently) says "paint any color on your wall within seconds...", which is in fact true. The problem is that more than just your wall gets painted if anything in photo is even remotely close to the same color pallet as the wall. The example bedroom shot they currently use has a high contrast headboard on the bed, which certainly helps. However, the photos hanging on the wall are to similar in color to the wall itself and would have certainly been blue as well. The creators would have had to first erased to blue off the hanging photos (using the built in eraser tool) and likely partially off the bedside table as well, prior to taking the final screen shot.
So while you certainly can achieve the results portrayed it certainly is a lot more tedious than "within seconds". So, since I was able to get the desired result (after about 5 minutes of carefully erasing) Ill give it 2 stars.
