Thinking of getting into warhammer, which paints should I get for Skaven?

I'm new to warhammer and do not own any paints, since I've been playing Total War Warhammer 2, I've enjoyed playing as the skaven so I was hoping to get the vanguard skaven miniatures, however I do not have the book that would tell me which paints to get. Which paints will I want for the skaven? And are there any cheap alternative paints that might also work well?
