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

[BoQsc]

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?
> C:\Users\Juozas\Desktop>rdmd color.d
> color.d(2): Error: module `console` is in file 'dmd\console.d' 
> which cannot be read
