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.
