Paint Color Visualizer

I like this app; it works easily and accurately. One suggestion would be to be able to zoom in or enlarge the pic. Thank you!

This app gives access to a lot of colors from different manufacturers. BUT it does not identify different elements in a picture effectively enough to let you change the color of a cabinet panel and a cabinet frame two different colors. In a single room, it only let you change the color of all the walls rather than having one wall, one color and having a different accent wall. It would be much better if I could tap on a photograph and then apply the color to the polygon where I wanted.

This looks like a very promising app to help me choose colors for my house. But I am interested in painting my house in two different complementary colors with the same trim for each color. Is there anyway to select one color for the top half of the house And a second color for the bottom half with a line of trim separating the two. It would be very useful to be able to select with your fingers the general area that you want painted in the color you choose so that you could choose to colors that would work well together. Also, it would be useful to know how to contact the developer with specific questions. What is the help procedure for this very inventive product?
