Why do the entries on the list preference not show up in the app?

view story

http://stackoverflow.com – In the settings section, there is a list preference (as shown below in the code) for colours but I can't seem to find the reason why the values don't show up. I have checked the internet but I can't seem to understand the difference between android:entries and android:entryValues. Could this be a problem in my code? Any help is appreciated. Thanks in advance.
