I have no experience with movies. But if it can be done in Photoshop, then it can be done with ColorWasher.
You'll see it's really simple to use. Only in some exceptional cases you need to tweak a bit yourself. And you always get interaction from the plugin itself as it tells you (box with text) what you're about to do. It even tells you if it would like to get a larger area to sample from.

Of course, if you could go back to that place and take a shot of a white sheet of paper under those same lighting conditions, it would be even better. You could use that photo to "calibrate" colorwasher as the plugin remembers the last settings you used.

I have been beta-testing it some years ago, when it went from v1 to v2 and I was confident that I could outperform it. I only found one pic after a long search that I could handle better. And most times the plugin was outperforming me.
Even today it's one of the only plugings I still have installed.

There are no Borg. All resistance is fertile.
