Ohhh! I see, the purple gradients are for Class E with a floor of
700', and that's why they show it separately.This really helps my
understanding.


It's magenta.



So does Class E have any special restrictions on unmanned free-
balloons?


Yes. Unless otherwise authorized by ATC, no person may operate an unmanned
free balloon below 2,000 feet above the surface within the lateral
boundaries of a Class E surface area. A surface area exists when controlled
airspace begins at the surface.




The FAA guidelines on unmanned free balloons says nothing
about airspace classes, only payload. I just thought it wise to avoid
the Class C airspace in my area all together.


See FAR Part 101- Moored Balloons, Kites, Unmanned Rockets and Unmanned Free
Balloons.
