Free paint software for mac

Nova Paint 1.0 is a highly-efficient, high-quality utility which will take a color specified either as RGB percentages or by the apple color picker and give back the value used for the ModVal value for Paint outfits in Escape Velocity: Nova by AmbrosiaSW.

Tux Paint 0.9.21 is designed as an effective paint program which is intended for young children (ages 3 and up). It has a very simple and fun-to-use interface, lots of sound effects, and a cartoon penguin who helps explain things.

A variety of drawing tools are available, including a set of 'magic' special effect tools, and a 'rubber stamp' (or 'stickerbook') tool for placing pre-drawn and photographed images into a picture.

Tux Paint is free software, released under an Open Source license. It has been translated into over 2 dozen languages, including Spanish, French, German, Italian, Chinese, Japanese, Korean, Greek and Hebrew. It also runs on Windows, Linux and BeOS.

Poster Paint is a simple painting application for Mac OSX, a bit like Microsoft Paint for Windows. It can read and save files in BMP, GIF, JPEG, PNG and TIFF formats. It has simple drawing tools but does not currently provide all the tools you might expect. New tools will probably be added to new versions.
The code is currently of early beta quality. There are a number of known bugs as noted in the bug list in the application. None of these crash the app (that I know of) or do anything bad to your Mac!
Poster Paint is a Universal Binary so will run natively on both PPC and Intel Macs.
Enhancements:
- Added icons for tools.
- Quick access to zoom via bottom right of window.
- Zoom menus can be customised easily.
- Undo options in Preferences.
- Upgrade to IconFamily 0.9.2 (removes 12 warning during compile).
- Zooming on images with alpha and/or with the grid showing is much much faster.
- Background for images with alpha and grid colour can now be customised.
- App can be quit if a new document sheet is showing.
- Crashes can be reported via built in crash reporter.
- Release now packaged as a pretty DMG.
