Using color -  particularly paint can be intimidating for many people.  Small chips don't always look the same when put on a large wall and they change when put next to other colors and finishes.  It may be hard to keep in mind an entire pallete of colors and finishes to visualize the whole experience. 

Full color renderings are great, but even with sophisticated computer programs, it isn't that easy to do a quick study for discussions with a client.  
We use a simplified process that works in most cases.  We prepare 3D sketches of the new design and place images of the proposed  colors and materials keyed to their location. 

Together with actual samples we can provide, our clients get a better feeling for the entire look of the space(s).  This allows use to quickly explore options and arrive at better solutions.
