[support] permissions? folders? files? newbie questions

[Dave Stevens]

"The specified file themes/bartik/logo.png could not be copied, because the 
destination directory is not properly configured."

then in the logfile, 
"http://69.90.112.112/d7/drupal-7.0/admin/appearance/settings/bartik?render=overlay&render=overlay

Referrer	
http://69.90.112.112/d7/drupal-7.0/admin/appearance/settings/bartik?render=overlay

Message	The file permissions could not be set on public://color/bartik-
a3e578e8/colors.css."

This doesn't help me. If I knew which permissions were the right ones I'd 
certainly change them but what ARE the correct ones and where is this 
"public://color....." folder.

and there doesn't appear to actually be any such folder as drupal-7.0/admin

Ideas? documentation?

Dave
