I found another trace of green that my other post didn't touch upon:
gtk-2.0/gtkrc
gtk-3.0/settings.ini
link_color:#A7BB85
(Under gtk-color-scheme)
(Nope, this doesn't "fix" it... 
)
@base_color seems to be defined as purely white (#ffffff):
./gtk-3.0/gtk-main.css: @define-color base_color #ffffff;
./gtk-3.0/public-colors.css: @define-color theme_base_color @base_color;
./gtk-3.0/public-colors.css: @define-color insensitive_base_color @base_color;
./gtk-3.0/public-colors.css: @define-color theme_unfocused_base_color @base_color;
Tip! Get the terminal to search through the files for you:
grep -r 'text_to_find' /path/to/files
So, I don't really know where the green is still coming from. I have a mix match of programs being green and most others orange:
Caja (I think is GTK 2) has orange buttons/outlines:
zenity --question and many other programs (again, might just be GTK 3 ones?) stay green:
