I don't understand what you are doing, I'm afraid. Are you familiar with the different between the RGB color space and the HSV color space? If not, Wikipedia can help you. Also, "green" can be a very coarse definition. There are many shades of green. I assumed you want the color where both the red and blue components did not exist.
