Github save diff to a file and share

I have a private Git repo that I cannot make public. I like to generate diff from my commits and ask outsider if my commits are good. To make him review my commit easy, I like color (red/green) to be applied to where my changes are. How can I save diff to a file?

print the diff between previous and current version into a file:

git diff HEAD^ > /tmp/mypatch

apply the changes to current working directory/branch:

git apply /tmp/mypatch

create a "patch" file out of the diff between previous and current version:

git format-patch HEAD^    # creates a file like "0001-descriptiong-of-last-commit.path

print each patch to a seperate file, e.g. to send it per mail...

git format-patch master

[a]pply [m]ailbox to git repo (e.g. git checkout -b myTestFromMailbox)

git am myPatchMailbox.mbox

difference between git apply and git am

git apply - takes a patch (e.g. the output of git diff) and applies it to the working directory (or index, if --index or --cached is used).

git am - takes a mailbox of commits formatted as an email messages (e.g. the output of git format-patch) and applies them to the current branch. (git am uses git apply behind the scenes, but does more work before (reading a Maildir or mbox, and parsing email messages) and after (creating commits).)

"git format-patch HEAD~" creates a diff for the last commit that you can send through email or as a file.

You can see more options on: https://git-scm.com/docs/git-format-patch
