LED Projector used to project background scenery for play.
Sounds like a tougher situation than mine. I often shoot speakers at seminars and they rarely move as much as a dancer. I try to get the screen to show up behind them and typically use bounce flash to illuminate them. The screen is usually far enough away so that the flash only illuminates them and has little effect on the screen.

That is helpful. I frequently photograph dancers on stage, hence the usefulness of a fast shutter speed. However, I would have been able to use a much slower speed for that particular play. I'll do better next time. I appreciate everyone's help.
I appreciate your replies. If I shoot in that situation again, I will give an update. I believe the shutter speed will have to be slow enough for a complete cycle of the projector's beam, whatever that is, and fast enough to stop action, what ever that is. That is where I will start next time.
Thanks all who replied!
The projector is using field sequential RGB colors
A very slow shutter (like the eye)might average them

At typical video 30fps, your 1/500 shutter speed may have caught the RGB changing. Maybe slow it down to under 1/30th.

At a theatrical performance, I recently took pictures with a Canon 1DX, settings 1/500th, Auto ISO. They used an overhead LED Projector used to project background scenery for the play. It was a money saver. The background appeared constant to the naked eye but the picture of the background had greatly varying wide horizontal color streaks.
During the performance I kept the focus point on the actors and their color was for the most part OK except when the projector's light was on them. It reminded me of a fluorescent light except it was in color. Usually a fluorescent light can be dealt with one picture at a time in processing. In this case the lack of uniformity within a single frame complicates the matter. Has anyone successfully dealt with this problem? Thanks!

Uhh, No. Read the other posts in this thread.
There is more to this problem than meets the eye.
