Joe, do you refer to the first or second reject in my last post? I have increased yellow saturation of the leaves in the second reject to better match colours of another picture taken some 20 minutes after the one I'm working at:
The tree species are different in these two pics though, so it's no more than a hint for me...
The funny thing for me is that only the green of leaves is weird but other "reference" colours are OK (like the patches of blue in the sky or the red on the second car or the grey of the concrete wall).
