there is some method to extract graysacle image from color image (rgb u32bit to grayscale u8)
but the standard method is use imaq casting image
because when you use extract color indeed there is some problem based on rgb filter on ccd and also bayer of camera by extracting color some feature will be hide and some other will be bold the thing that maybe is not real image of site that you get photo (of course sometime we extract a color for find ESP particle or place or remove noise )
bellow image show the vi that you have to use to get standard u8 from u32 image also other method exist for this one but it is simple method
by the way your coding is so messy and you have to clean up

Problem is, if you use Vision Assistant you have only one option: Color Plane Extraction
What i don't understand is, why NI did not add the more correct solution under "Processing Functions: Color".
