Application Color schemes

I am working on a new开发者_JS百科 UI for an existing application, currently in VB6, and have been told to make it look better / pretty.

Is there anywhere I can get some good ideas around colour schemes for a business application which are not 25 shades of grey?

FYI: I am working in WPF.

Check this application (for taking color scheme)
