Hi Andrew, could using an auto command on the "DiffUpdated" event work for you?

Example: add this to .vimrc:

    au DiffUpdated * if &diff | colorscheme darkblue | endif

This function will be executed every time "diff mode" is updated in any way and
seems to work both when running vimdiff directly and when entering diff mode
interactively (as it is the case now when running "git mergetool").

It has the added benefit that you can also use this same "trick" to toggle the
settings off when *exiting* diff mode:

    au DiffUpdated * if !&diff | colorscheme desert | endif

Let me know if this is enough for your use case.

Thanks!
