Color Blasts and Hue and Saturation

Please forgive me if this is a stupid questions, however, I have a gig coming using a Hog IPC and many color blasts. We are also using the PDS-750-TR. I want to use the hue and saturation feature, however, it does not seem to work . I can only bring them up with intensity(which brings up everything. or I can bring up each individual RGB color. what am I missing. I feel stupid not knowing, as I am sure it is somthing simple.
I would be greatly appreciative to any thoughts on the matter

thanks:confused:
