How to change a colour of header bar in Chrome for Android

I ended up other day being on BBC page. I was browsing it on Chrome for Android and I noticed something strange.

The colour of address and header bar was red!

"Wow! That's cool", I thought. Seconds later I started to ask myself how did they do that.

Turns out it is a very simple thing.

All what you have to do is to add this meta tag:

<meta name="theme-color" content="#FF0000">

Replace the content attribute value with your colour and voila!
