book and chapter icons a touch more different?

very low priority - Would it be possible to make the colors of book and chapter a bit more different? It is sometimes not easy to spot a book if there are chapters around. A lighter hue for the chapter or a darker blue for the book would help. The other icons are great to distinguish.
