Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I think that what you want is to shoot without histogram alterations in the color balance?
If so - given that your model of camera has such a choice - you ought to either set a default White Balance to shoot with - with all colors equally weighted.
Or, shoot in a mode which disables the Film Simulation choices altogether. (I take it that the 'Normal' or 'Provia/Standard' Film Simulation isn't acceptably neutral.)
