Let me add two things to this madness that come to my mind out of the bat:
- observer metamerism (somewhat obvious)
- I don't have a name for that, but once (at some point tried it again and couldn't reproduce), I dragged a window between my 2 monitors. As it was mostly on the 2nd monitor, the image colors suddenly shifted in hue. Not just on the 2nd monitor, on the 1st one too. And the colors were obviously wrong (way too purple) on both monitors.
