My editor choice is Visual Studio Code since the first beta release.
I like personalize everything in my editor and Visual Studio Code is perfect in this way.

Here I will show my Top 5 favourite Visual Studio Code theme.

Night Owl

One of the best theme for Visual Studio Code (and others editor!!!).
This is my current theme for work.

Winter is Coming

Developed by John Papa from Microsoft, I love it.

Shades of Purple

Well documented and professional theme. Awesome!

Rainglow

Many color themes!!! Try it!

Noctis

My second favourite theme, after Night Owl.
This is the best to relax your eyes after a long working day.

Plus

Power Mode

It's not a real theme, but I like this effect when I have a presentation or a demo with customer. :)
