Conproco revolutionizes color matching of natural stone. It is no longer necessary to take a sample of the stone from the building and send it to us for matching. Simply have one of our sales reps (and many of our dealers’ sales staff) place the Color Eye onto the surface of the stone. The hand-held Color Reader records the color values which are then download onto our app using your cell phone. The app has access to our color data base. It provides a match with an existing color in our data base. A sample of the match can be requested by completing a form on our website or forwarded to a Conproco Kiosk dealer who can produce a sample without delay. This capability reduces weeks of processing and expense to just a few minutes.
