Well, I DID say it was an ugly green! :D They changed either the general lighting color or set color or something in the filming as S6 has been remarkably green. The coloring approaches I'd used on previous seasons' caps went that ugly green in S6. Looking back, I obviously needed to change the background out for a texture.

Think how much better the third one would be with a real background rather than one I chose to fade to black because that green was so "off."
