Pan Shizhu's color scheme ps_color script#760 supports two styles, a cool (dark) and a warm (light) style. If you want to switch between these styles by just a single key stroke, you may define the following function in your vimrc:

function! s:SwitchPSCStyle()
  if exists('g:psc_style')
    if g:psc_style == 'cool'
      let g:psc_style = 'warm'
    elseif g:psc_style == 'warm'
      let g:psc_style = 'cool'
    endif
  else
    let g:psc_style = 'warm'
  endif
  colorscheme ps_color
endfunction
map <silent> <F6> :call <SID>SwitchPSCStyle()<CR>
