Hi EyeZik,
I would try using the IMAQ Extract Color Planes VI to get greyscale images that represent the red, green, and blue intensities, respectively. This VI can be found by going to
Vision and Motion»Vision Utilities»Color Utilities. You can then find the average of the pixels in an image by using the IMAQ Linear Average VI. This can be found at
Vision and Motion»Image Processing»Analysis. This should allow you to quickly get an average for each of of the primary colors.
