How do I colorize iex?

How do I configure IEx colorization, complete with syntax coloring, as shown in the examples in the Elixir Guides (Introduction — Elixir v1.16.0)? I’m on a Mac using zsh. Thanks

I am using IEx.configure, but I don’t get all the colorization that I see in the Elixir guides. I’m guessing at this point that the colorization isn’t coming IEx interaction but is being added as part of the formatting of the online guides.

Here’s mine if that helps

What is the result of echo $TERM ? You might need to enable 256 color in the terminal settings, or upgrade your terminal to one that supports it.
