In addition to photoshop, I also do color correction for movies. Viewing the sequence on a calibrated display in a dark room one can start to "neutralize" the colors and as one continues in the image sequence, start to drift from the original color balance.
But there are a few tricks:
1. for movies, I tend to compare the later shots in the sequence to the first shot in the sequence, and also to the previous scene to keep consistency. In photoshop one could have a "reference" image open in photoshop, and from time to time, switch back to looking at that image. It could be a small jpeg, just for screen viewing.
2. Don't work in a completely dark room. Have a "bias light" illuminating the wall behind your display set to be close to the color temp of your calibrated display. (I'm assuming a white wall, but you could also paint it a neutral gray). Another trick I use here is to open my calibrated laptop screen to display a white screen and place it behind and near my computer display. This serves as a constant reference to D65.
3. Don't have bias light or a laptop handy? Every once and a while make your photo small on your display in photoshop and set the photoshop GUI background to white. When viewing your photograph against the calibrated white reference, you'll get your eyes back on track. Also this helps to keep to your perspective for printing (as if viewing your print in a white matted frame) and helps one not get seduced by the emissive display and make your images too dark for a good print.
4. An old timers movie colorists trick is to once in a while view your image in greyscale for a few minutes to keep your sense of color from drifting.
And one last thing that I do is to always make my conversion from RAW a little bit low in contrast, and maybe saturation. Then, once I'm working in Photoshop, I can adjust the image to any look without needing to go back to camera RAW (or lightroom) again. But, for me, to paraphrase Ansel Adams... RAW conversion is the score and photoshop is the performance
