Linux / Folder and /root folder

I searched now a while but couldn't find an answer to this question.

I have a Linux based server (centOs).

In the root folder (/) i have a folder called root (/root).

Now when I sudo cd root/ i stay in the same folder (/).

First I thought that /root is a symlink but symlinks are cian blue and here I have dark blue.

I've read that the /root folder is the root user folder but I don't get in it.

Can somebody please explain what is going on here?
