KolourPaint is a free, easy-to-use raster graphics editor for the K Desktop Environment.
It aims to be conceptually simple to understand, providing a level of functionality targeted towards the average user. KolourPaint is designed for daily tasks such as:
* Painting - drawing diagrams and "finger painting" * Image Manipulation - editing screenshots and photos; applying effects * Icon Editing - drawing clipart and logos with transparency
In version 3.3 of KDE, KolourPaint replaced KPaint as the standard simple painting application. It is shipped as part of the kdegraphics package.
It is good replacement/substitute to MSPaint with a similar layout, but more advanced features. 
KolourPaint can also run in desktop environments other than KDE, such as Xfce and GNOME, as well as window managers like Fluxbox. The prerequisite packages can be installed automatically, and Kolourpaint only needs a small portion of KDE to run.
