Color Picker is designed for ultra quick access and to quietly get out of your way when you are done picking. The color will be available in the pasteboard. Color Picker resides in your menu bar once you have launched it. When you press the icon, it will immediately freeze the screen, starting to track your mouse and the color beneath it. It will show a resizable zoom-in window displaying the area around the mouse pointer so that you can select a single pixel with great precession.
