thats a very tough problem as any non-incandescent bulb source doesnt have a smooth frequency output - but spikes at certain frequencies.
matching the light frequency response on cameras to projectors is not trivial - if it doesnt just work.
any green or brown shift - is most likely to be ageing bulbs -

projectors are not designed to be light sources.
