PixelValue
Shows the color value and HTML code of a pixel under the mouse cursor
... information in the console (mouse cursor position, RGB value of the pixel under the cursor, HTML color code) press Alt. To disable it press Alt again. To save all the tracked mouse clicks to a table in a .html file (this file is called output.html, and is created automatically in the folder where the .exe file is currently located) and display it in your default web browser, press the middle mouse button (the mouse wheel).
That's pretty much it...:D
