This is a screen Pipette it is a very simple tool that is over-engineered using WPF. It was developed to allow you to get the RGB or Hex value of any value on the screen. Since I develop on 3 Screens it supports multiple screens and works by simply docking the application to the screen, this will make sure its always on top then press F5 when over the item you want to get the hex for. The application has a display of the current colour you are hovering over so you can accurately select the colour.
