Using Blender 3d for FX

i’ve been trying to use Blender for FX purposes lately, and i love it. I had no idea that you can do Chroma Key straight from the compositor.
however, when i tried doing an explosion with the smoke simulator in 2.5 with the green screen effect, the smoke was all green.

there’s not any tutorials on FX in Blender so I have to find it all out myself.

any help?
