"striking" light observations

1
I’ve always heard and known that fluorescent lights are tinted green and will show up as green when you film them. But it wasn’t until this weekend when we were filming a project that I really noticed. We were in Bear Hall shooting some scenes in the hallway. We left the fluorescent lights on but added other lights and gelled them to bring out other tones. But when we got the shots we wanted and turned those other lights off I was standing there and saw the hallway and everyone in it turn from a warm yellow to a cold gross green. And that’s when I saw what everyone had been talking about.

I have a really bad habit of leaving my bedroom lamp on when I leave the house. But while I’m wasting precious energy, I’m also able to observe the shadows, the light and the contrast that the lamp makes on the blinds in the window. The curve of the lampshade is dark but as soon as the light gets to either the small opening in the top or the large one in the bottom it shoots out and lightens the dark. It’s kind of hard to explain but from the outside, if you didn’t know what it was you might think there was a solar eclipse going on in that room.
