Krita is a free and open-source raster graphics editor written in Qt and designed primarily for digital painting and animation purposes. It was developed by KDE, an international free software community who develops Free and Open Source software and is written in C++.
This open source cross-platform application offers an end-to-end solution for creating digital art files from scratch and is optimized for frequent, prolonged and focused use. It is made by artists that want to see affordable art tools for everyone- concept art, texture and matte painters illustrations and comics
Krita has several features that are unique or a first among free software painting applications: support for colorspaces other than RGB, like CMYK, support for HDR painting, painting assistants, a perspective grid. The Krita developers are keen to support the artistic community that has grown around Krita. It is designed primarily for concept artists, illustrators, matte and texture artists, and the VFX industry.
The most prominent feature of Krita is arguably its UX design with graphics tablet users in mind. It uses a combination of pen buttons, keyboard modifiers and an icon-based HUD to ensure frequently-used functions can be accessed by fewer clicks, without the need to search through text-based menus.
