Select and go to effect, keylight, and select a matte, change this view to a status view, change the screen gain just a little bit, change the screen balance, only a tad, and if your colors don't look like mine, that is perfectly okay, it really depends on which screen color you chose.

If, however, we are using the mask to keep something from being affected by the key, this mask is called inside mask. When we need to narrow the part of the video that is green with a subject, those masks are known as garbage masks, or outside masks.
