I can refer to this answer I wrote recently about color correction:

90s film look

The basic principle is alway the same: You take the sample texture and apply any kind of edits to it with an image editing application. This includes hue shifting of course. This could be done with a dynamic editor extension like that replicates the functionality of your GI$$anonymous$$P picture. In that case, I would make a copy of the sample CC sample texture, set it to read/write enabled as usual, and then the Editor Extension lets you shift hue etc, and when applied, copies the pixels from the original sample texture over the copied one (so we always have a clean slate), and then use any kind of color changing code for each pixel. Lastly, this edited texture is converted to a 3d texture nad used for the CC script of the camera.

@fpsgeko You can do this in Unity.

In UnityStandardAssets.CinematicEffects, there is a script called ToneMappingColorGrading. Under Color Grading, you can select the hue, saturation, vibrance, tint, and a whole slew of features. Just apply this script to your camera and you are good to go.

You can also access these through scripts if you want to change the values on the fly.

@fpsgeko If I understand correctly, you wish to modify the camera's view to change the coloration of everything seen. I don't believe this is possible within the camera, but you can change the lighting in scenes to be certain colors and hues.
