Hello, i have choosed a light wood for the library because i think that it helps to create a warmer atmosphere to the room (and is also relaxing for reading a book!)...
I have done also a render in white acrylic material in order to give you an idea of what will be the effect (probably seeing the house style this solution will be better...) it's up to you decide which material is the best for your needs!
However here are the links of the two animated GIF (you can find them also on the tables)
