These are some simple steps to follow, hope it will be helpful.

1. Open a new chrome tab, type chrome://flags

3. Click the "enable" link
   
4. Click on "Relaunch Now" at the bottom of the page.
   
5. After restarting Chrome, open DevTools, DevTools settings, and select the experiments tab.
   

Now select the experiment you want (e.g. "Allow custom UI themes").

You need to reload devtools after: Alt-R will reload devtools itself, or you can just close and reopen it.
