How to save Vim bg color setting?

view story

http://askubuntu.com – I'm learning Vim for programming on my lubuntu laptop, but the dark blue color for comments makes my eyes melt. It looks better when using :set background=dark but it does not seem to remember this between sessions. I am a bit scared of changing the syncolor.vim file. Is there another way to make Vim remember this setting? (HowTos)
