MultiColor is an image manipulation tool for Commodore 8-bit computers' 
graphics formats. It is an old-school painting program for graphicians but not
an image converter. Currently VIC-II multicolor bitmap is the only supported
image format.

Features:
- Written in C++, so it's quite fast and no special runtime is required
- Can be compiled for many platforms, because it uses wxWidgets
- Can load Koala and Amica, file type is detected independently from file name
- Behaviour when hitting the color-per-cell-limit can be selected
- Undo/redo
- Tools with realtime preview (e.g. Line)
- Basic TV emulation
- Zoom, with grid at higher zoom factors
