What we are going to do is to recolor our Image blue. At Image Magick you would select Color from the Pull Down Menu, Flood Fill, and enter your color choice. Then just click the Image and move the Arrow to the pixel you wanted to recolor. This will recolor the selected and all contiguous pixels to the chosen color.
Choosing Matte will make the selected and contiguous pixels transparent.
