Read the "scribble" example in the tutorial. Drawing areas don't
remember their state, you have to handle expose events.

7.2 is not really right IIRC. You want to use the color allocation. 

Or as I suggested to someone a couple days ago on either this list or
gtk-app-devel-list, use GdkRGB to allocate colors instead of
using colormaps directly. Check the recent archives for that.
