How to load a different colorscheme when doing vimdiff.

I want this because the my current colorscheme does not show some diffs properly in vimdiff, For. eg some diff is shown with same fg/bg color. This makes it very hard to understand the diff. So every time i do a vimdiff i have to do :colorscheme some_other_scheme

Can this be done in .vimrc file?

I don't know why vim uses so many colors to highlight with, it doesn't really help you figure out what's going on.

I modified my colorscheme to only use one color to highlight (with another to show where theres a difference within a line) and it made all the difference.

Before

After

I did this by adding the following to the end of my colorscheme file (~/.vim/colors/mycolorscheme.vim).

highlight DiffAdd    cterm=bold ctermfg=10 ctermbg=17 gui=none guifg=bg guibg=Red
highlight DiffDelete cterm=bold ctermfg=10 ctermbg=17 gui=none guifg=bg guibg=Red
highlight DiffChange cterm=bold ctermfg=10 ctermbg=17 gui=none guifg=bg guibg=Red
highlight DiffText   cterm=bold ctermfg=10 ctermbg=88 gui=none guifg=bg guibg=Red
  • cterm - sets the style
  • ctermfg - set the text color
  • ctermbg - set the highlighting
  • DiffAdd - line was added
  • DiffDelete - line was removed
  • DiffChange - part of the line was changed (highlights the whole line)
  • DiffText - the exact part of the line that changed

I used this link as a reference for the color numbers.

Note: I didn't set the gui options because I use a different colorscheme for macvim/gvim
