When I move my eyes around the screen, I see orange and blue flashes. This is particularly noticeable on black and white material (since the orange and blue shows up well) and also on high contrast images. Is this the "rainbow effect"? Is it normal, and is there anything I can do to minimise it? I have attempted to capture this on film, by using the moving white bar test pattern. One shot is panned with the bar, the others are panned against its motion. You can see the orange and blue edges, but when viewed for real, the orange and blue bits seems to appear further away from the bar. The "orange" is orangey-brown, not the greeny colour that seems to have come out on the photo.
