Vim CursorLine color change in insert mode

Question

There is good snippet for changing cursor color:

if &term =~ "xterm\\|rxvt"
  " use an orange cursor in insert mode
  let &t_SI = "\<Esc>]12;orange\x7"
  " use a red cursor otherwise
  let &t_EI = "\<Esc>]12;red\x7"
  silent !echo -ne "\033]12;red\007"
  " reset cursor when vim exits
  autocmd VimLeave * silent !echo -ne "\033]112\007"
  " use \003]12;gray\007 for gnome-terminal
endif

How should I alter this that instead of cursor, CursorLine would change color for example from dark blue to blue?

Have you look in into the 'highlight' command which is a easier way to control this.

For example, to change the CursorLine,

:hi CursorLine guifg=red guibg=blue

Reference: :help highlight

To make it switch between mode.

" Enable CursorLine
set cursorline

" Default Colors for CursorLine
highlight  CursorLine ctermbg=Yellow ctermfg=None

" Change Color when entering Insert Mode
autocmd InsertEnter * highlight  CursorLine ctermbg=Green ctermfg=Red

" Revert Color to default when leaving Insert Mode
autocmd InsertLeave * highlight  CursorLine ctermbg=Yellow ctermfg=None

I may be possible to mix termcap color with autocmd, but IMO, highlight is more easy to maintain in long term (and in case if use gVim occassionally)
