It looks almost flat (no shadows or gradients), clean, simple and elegant. FlatLaf comes with Light, Dark, IntelliJ and Darcula themes, scales on HiDPI displays and runs on Java 8 or newer.

The look is heavily inspired by Darcula and IntelliJ themes from IntelliJ IDEA 2019.2+ and uses almost the same colors and icons.
