I guess the color navy qualifies as "blue" since when I brought the image into Photokey2 it not only removed the blue background against which I photographed Larry, but also much of the dark blue. I had to copy the navy shirt from an unprocessed picture and then paste it over the one with the background. This shot would have been easier had I used a green background, but I don't have one AT THE MOMENT. I am really enjoying the chromakey method of replacing backgrounds.
