If nobody knows for sure, why don't we just check? I have attached a 
small application that will draw all the different bezel versions and if 
somebody with an OpenStep or Cocoa system runs this and sends back a 
screenshot of the resulting window we should know. If the Light and Dark 
variants are sensitive to defult colour settings they need of course 
tests with different values in the system colour list.
