Most stores I have been to in my hunt to match a certain paint color have requested a chip about an inch square to computer match the color. Even this, it is sometimes not right. When we needed paint matched perfectly recently as we were touching up our walls in preparation of our house being put on the market, my contractor recommended Kelly Moore. I had a tiny piece for him to see and didn't think it would be enough, but he assured me it was fine since he used his eye to match and not a computer. I thought to myself, this isn't going to work, but when I picked up the paint it was perfect. This saved us from having to pain the whole house! What's even more astonishing is the fact that this young man was in his 20's and couldn't have too many years experience. But he did great work!
