I don't deal enough with video/RGB calibration to know what the best solution is. After a while I guess it just starts to be like 'The Matrix'...I look at that almond color and I see a brilliant snow white...look at that ugly brown and see a vivid lemon yellow. I can certainly get by with it. But a good solution to me would be something like 'my pallet' in LSP where I could assign node RGB values and coordinate that with monitor RGB values to net the same color...ie on my monitor I would see 255, 255, 255 ...snow white and when I click that color, it would send 255, 208, 107 to the nodes.
The fastest way I've developed to edit transitions, is to get the avi in a video editor, tweak the color setting, do a screen capture, look at the image in a photoshop program with the 'color selector' tool - so I can directly see the RGB values, tweak a bit more in the video editor, screen cap, check RGB's, etc. After a few iterations, you get the transition relatively close to the proper RGB values for the nodes and save it. The video on the screen looks like junk, but it plays out beautifully on the nodes. It works, but you'd think there would be a much more elegant solution!
As far as one 'fix' for the whole thing. Again, I'm no video/RGB expert, but in trying for a 'one step fix', I grabbed the image with my three sample colors, opened that in Paintshop and found that choosing Adjust > Brightness and Contrast > Curves, then tweaking the RGB curve actually pulled those colors somewhat close to the nodes output. I don't know if this would 'globally' fix all color mismatches, but got the three examples fairly close:
