Around your autocommand:

augroup filetype_colorscheme
au BufEnter *
\ if winnr('$') == 1
\ | if !exists('b:colors_name')
\ | if &ft == "vim"
\ | let b:colors_name = 'color_dark'
\ | else
\ | let b:colors_name = 'color_light'
\ | endif
\ | endif
\ | exe 'colorscheme' b:colors_name
\ | else
\ | colorscheme default
| | endif
augroup END

or (maybe more readable)

function SetColors()
if exists('b:colors_name')
exe 'colorscheme' b:colors_name
return
endif
if winnr('$') > 1
colorscheme default
elseif &ft == 'vim'
colorscheme color_dark
else
colorscheme color_light
endif
let b:colors_name = g:colors_name
endfunction
augroup filetype_colorscheme
au BufEnter * call SetColors()
augroup END

This way, the autocommand will be defined unconditionally, but if it
finds that at BufEnter three are more than one window in the current tab
it will go back to the default scheme.
