If you want a different theme and syntax highlighting for your code in Eclipse, or if you are just tired of looking at text at a white background and want to try something new, you can easily switch to a different theme.
Download and install the Eclipse plugin called Eclipse Color Themes. It can also be installed via the Eclipse update manager:
In the top menu, go to Help -> Install new Software -> Add source
and enter the plugin url (like pictured): http://eclipse-color-theme.github.com/update
