1. From your Admin Console, go to Extensions--->Template Manager
2. Click "paradigm shift" template, you will be taken to the settings
3. On the right hand side look for : "Highlight Color" : You can change this to any HTML Color ode to get the required effects.
Caution : Just remember to note down the default blue code number [063B5E]. You might want to put it back later
Hope this helps!
