Strange lighting effect

Hello there. I recently was looking in the toolbox. and found this.

I was wondering how any why the lights are doing this. It might be a but I have a feeling my studio is broken or something.

Doess this happen to anyone else or just me?

Never mind I found out why it was happening. Thanks.

Please mark your second post as the Solution, but also inform us what the fix was so that if anyone searches for this problem your post could help them.

The problem was that the Color Setting on the light was set to negative. It’s quite an interesting effect.
