A small note that may help. If you want to change folding colors: If you use gvim:
:highlight Folded guibg=grey guifg=blue :highlight FoldColumn guibg=darkgrey guifg=white
But if you use vim from the terminal:
hi Folded ctermbg=black
My settings in vimrc:
colorscheme desertEx "some modifications to the colorscheme "to view current settings use for instance ':hi Folded' set foldcolumn=3 hi FoldColumn ctermfg=216 hi FoldColumn ctermbg=black hi Folded ctermfg=216 hi Folded ctermbg=black
