whilst at work today i was thinking hard (honest) and staring up at the flourescent lights.After a few moments i looked away and noticed that i could see a large light spot on the wall, the colour of the light was not white, it was green! with a reddish outline!So i again stared at the light to see if i could repeat the "vision", and i did! In doing this again i noticed something else. When i was staring at the flourscent light, even before i looked away it began to look a light green.Why is that?

Ordinary fluorescent lights are green (you can get daylight balanced ones, but I assume we are not talking about those) - .....
This is also one of the reasons why the medical staff in an operation room wears green. After fixing their eyes on the parts of the open body, generally read, they would see the same objects in green when they look up. But as everything around is green (or mostly), they can rest their eyes when they look up.
