Green Tint used in music videos and movie

[Yellow Diamonds]

Hey Guys,

I am new to this forum, I am looking to achieve this look that is used in alot of music videos and movies.

Here is an example:

In this The Game video they used it quite a few time, wonder if its CC or just a projected green light. Does anyone know how to?

I included some grabs at the bottom

I'm guessing its most likely green gelled lights. The most telling one is the top right grab - his face is a different color temp from the background. If you color correct with a green tint then everything will turn green, unless you use selective color correction which can be quite time consuming
