FunOS

Krita is a powerful open-source digital painting application designed for artists who want to create professional illustrations, concept art, comics, and textures. As FunOS is based on Ubuntu, you can easily install Krita using either the official Ubuntu repositories or a Personal Package Archive (PPA) that offers newer versions. In this guide, we’ll walk you through both installation methods so you can choose the one that best suits your needs.

What is Krita?

Krita is a feature-rich painting and drawing program developed by the KDE community. It provides advanced tools for digital artists, including customizable brushes, layers, vector tools, and animation features. Krita is known for its intuitive interface and powerful brush engine, making it a popular alternative to proprietary tools like Adobe Photoshop and Corel Painter.

In addition to painting and illustration, Krita supports features such as HDR painting, Python scripting, and compatibility with various file formats like PSD, PNG, TIFF, and OpenEXR. Its strong focus on usability and performance makes it one of the most capable free digital art tools available today.
