Color Use

I like the use of brown in this ad. It reminds me of a library with custom made, solid wood bookcases. It has a sense of a regal environment for top of the line books. 

This is a book cover for Blue Note records. I think the blue is overused. I do like that you can ALMOST piece together a musical note from the rectangle on the top with the oval blending off the left of the page. I would have colored just the musical note in blue to not appear to overdone.
