macOS 10.15 comes with a very old version of the diff command. I've read in https://unix.stackexchange.com/a/338960/80391 that version 3.4 contains the --color argument.
How can I update the version on macOS so that I can use this newer feature?

1You'll have build it from source and add it to your environment. You can get the source code here: ftp.gnu.org/gnu/diffutilsNasir Riley– Nasir Riley2020-06-06 21:51:53 +00:00Commented Jun 6, 2020 at 21:51

Since macOS does not include a package manager, you have to install one if you want newer versions of the tools that come with the OS. The most popular one these days is Homebrew. Macports is a similar project.
After installing Homebrew, you can install a newer version of diff by installing the diffutils package:
brew install diffutils
Of course you can also build everything from source, but using a package manager is easier.
