Is there a relatively painless way of replacing the grey color used for the windows in OSX?
Ideally I would like to change the color used by individual applications, and have the changes stick after restart.
Any links to apps that do this would be appreciated, or to more granular methods. CrystalClear Interface is one app I have heard of.

Running Snow Leopard.
