Could you please post a photo?

Quite gloomy at the moment:

I would paint walls in white or ivory to bring more brightness. Or if you have wallpaper on walls get a lighter ones.

I will do that, thank you for the rendering

you are very welcome!

BTW, what computer program did you use? So handy!

Celerygirl's rendering are soooo helpful! Really helps to visualize the room in another colour. Love the idea of a warm ivory. If you want to go with a white, I suggest BM's Chantilly Lace. It's a very bright white with little undertone. As for your arched bookcases, I don't think they look dated at all. They're beautiful! Google "library with arched bookcases" to get decor inspiration.

I would also look at some samples with a lower LRV that may help add some warmth. Are you adding sufficient lighting to help? If the bookshelves are well constructed and trimmed out, I think they will look lovely once everything is painted out.
BM gentle cream LRV 71 or BM Navajo white LRV 78

Thank you so much ladies! I will go with a creamy white and I booked an electrician to see if he can install LED lights in the recess! I'm finally getting excited about this room!
