Shooting fluorescent lighting is bad if you wanna compare colour, because depending on which phase of the 50 Hz you are shooting, you will get different colour white balance.

(FYI the fluorescent lighting is flickering at a frequency of 50Hz because that's what our power supply is running at.)

Sorry if this has been pointed out before...

Actually, using a fluorescent light is not the best choice of light source to show flaring or ghosting.

Reason being fluorescent lights flickers! We can't see it with our eyes as it flickers much too fast for us but the camera is able to capture as it goes through its cycles.

Those yellow or sometimes brown colour patches are caused by the flickering of the tube. You can try it. Set your cam to continuous shots, aim it at the tube and fire away. You can get similar kind of yellow or brown patches in some of your shots.
