What is "dmd" Internal API, can I use it just like std Library Reference?

[BoQsc via Digitalmars-d-learn]

Hello everyone, again,

I had an idea that I want some colors in the output of Command 
Line (For Windows) and
the Terminal (For Linux)
I found https://dlang.org/phobos/dmd_console.html and wanted to 
use it.
But it seems I'm not being successful, and I do not understand 
why.

Here, you can see that I'm trying to import dmd.console;

import std.stdio : writeln;
import dmd.console;

void main()
{
    writeln("Hello World");
}

And the output says that, dmd.console; do not exist?
What are these Internal APIs for?
