default vimdiff color schemes are bad!

[Ryan]

I love vim. But vimdiff is useless to me right now because the default
color schemes make some text unreadable (bg and fg colors are to
similar). Has anyone devised a color scheme file that makes vimdiff
pretty or at least legible? I'd rather not have to burn an afternoon
making my own, but I will, because vim rocks!

This is what I use on black background:

highlight DiffAdd cterm=none ctermfg=bg ctermbg=Green gui=none guifg=bg guibg=Green
highlight DiffDelete cterm=none ctermfg=bg ctermbg=Red gui=none guifg=bg guibg=Red
highlight DiffChange cterm=none ctermfg=bg ctermbg=Yellow gui=none guifg=bg guibg=Yellow
highlight DiffText cterm=none ctermfg=bg ctermbg=Magenta gui=none guifg=bg guibg=Magenta

Rather than rely on the background being black, you might want to
explicitly use *fg=black.

Best regards,
Tony.

Writing a colorscheme is not difficult, especially if you don't deviate
much from the default: every default color you use means the
corresponding highlight group can be omitted.

I'm attaching my "almost-default" colorscheme: it's probably not exactly
what you need but it can serve as a source of inspiration. Drop it into
~/.vim/colors/ (or, on Windows, ~/vimfiles/colors/) then modify it as
you see fit.

Best regards,
Tony.
