Color sampling vis PS the black gray portions in RGB tend to be about 80-100 in all three colors in other words true grey. That seems to be the predominate sample I get but in some places there's 5-10 more of any given color depending on lighting it seems.
The portions I see as "green" come up as pretty uniformly as 90-100 in Red and Green and 68-80 in blue. So a sort of muted yellow-green which is what it looks to my eyes.
I only went and checked in photoshop as I know not to trust my eyes, although I've gotten pretty good at compensating for any minor color recognition issues I have.
WTF....
