With the IMAQ functions it's easier and a lot quicker to work with Monochrome images (greyscale) and so when you do extract an image you will end up with a greyscale image. This image will have a hight intensity value where the yellow colout was and low intensity value where the colour wasn't present. I believe that this is exactly what you will need to use the more advanced functions. (which you will probably need)
What are you expecting to do with the image after this point?
