        FlatLaf - Flat Look and Feel

============================

**FlatLaf** is a modern **open-source** cross-platform Look and Feel for Java

Swing desktop applications.

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 (LTS and latest).

The look is heavily inspired by **Darcula** and **IntelliJ** themes from

IntelliJ IDEA 2019.2+ and uses almost the same colors and icons.
