title: How to change the eclipse window colour based on the workspace?
body: <p>If I'm working on live branch as well as development branch at almost same time, 
  naturally the code in both the branches is similar, 
  my two eclipse instances are open at the same time, 
  I keep swapping between them and tend to commit mistake by adding code in the wrong workspace.</p>
  
  <p>To distinguish between the two instances of eclipse if I could have different themes (colours), it could have been good fool proofing measure.</p>
  
  <p>I would like different theme for the eclipse window than the code font or file background.
  I use same eclipse (Helios) .exe for different workspaces.</p>
  
  <p>Any simpler advice could also be helpful.</p>
  
  <p>Thanks in advance.</p>
