I'd like to reskin a Silverlight app to be more visually compelling. Unfortunately, I went to school for computer science, not design, and I have trouble deciding if two colors even match. How do I get started? Let me add that time and money are both factors so pursuing a design degree isn't an option (though it might be ideal).
EDIT: I also need to learn how to implement good design, so any guidance on the toolsets (Blend or Illustrator?) would be helpful too.
