Add two chroma key to green screen?

[iharpyou]

Chroma key is like color sampling, no matter how hard I try it is not perfect however
if I could get two green samples it would be great. Is there a trick to have chroma key sample green from the different sections?

You could try Chroma Key: Simple for one green color, then Chroma Key:Advanced with “Operation: Minimum” for the other color. That might work.

I was able to use Chroma Key: Advanced just once.
