1.check cut,copy and paste works.
2.check whether the default background color is white.
3.check whether zooming works.(all menu items work)
4.check whether the selected color is displayed.
5.check whether the colors can be edited.
correct me if i am wrong.I hope all these comes under functionality testing,
As a startup process I would recommend you to do an exploratory testing of the application by recording the tasks via badboy (www.badboy.com.au) which will help you to re-run the test cases and cover full functionality.
