A touch of Lilac is a vibrant theme with a UI that takes you through the different color shades of the lilac flowers.
VSCode → File → Preferences → Color Theme → Select "A Touch of Lilac Theme"
The font that I use and that can be seen in the screenshots is Courier Prime Code a great font that is code-optimized for programmers. If you want to give it a try, download it, install it into the system fonts folder and add it to your User Settings.
VSCode → File → Preferences → Settings → User Settings:
Recommended custom settings/extensions that I have in the User Settings on my side, in order to get the look as in the screenshots.
Of course there is the possibility that some things for this theme aren't optimized or maybe something is buggy, so don't be shy and let me know by opening an Issue or creating a PR.
I hope you'll enjoy the theme. Thanks!
