ColorDropper provides a small and easy-to-use tool for quickly obtaining the code of a target color.
It is very responsive and displays both the Hex code and the RGB as well as providing the exact position of your mouse cursor on an X, Y axis.
ColorDropper continuously polls for the active color and you can easily stop and start this process within the menu options. You can also set the window to the top of the screen or allow free positioning if desired. There is also a screen magnifier located in the lower right-hand corner for more pin-point color targeting.
