normally i would say green, but since you want a white back, then use that keying needs a lot of knowhow, and good keyers, and for some applications thats the way to go. the look you are going after a couple of well placed lights and you are done, for green you will need more lights a good keyer and you might still have spill, and other problems.

if you decide to go go with key i recommend advantedge ultimatte very simple very powerful
other keyeres keylight most keyers that come with your nle will make you struggle
