This is a theme package for IDA 7.3+. It was adapted from the VSCode theme in IDASkins.
Go there for screenshots etc. This was just a quick port with a few small changes to my liking.
To install just clone this repo into idabin/themes (IDA 7.3)
For IDA 7.4+ (built in theme engine) clone the theme into ~/.idabin/themes (mac/linux) or %APPDATA%\Hex-Rays\IDA Pro\themes
