What a beautiful space! Lucky you! Since it has very dark floors and gray walls I would have to paint it a cheerful color. I would also remove those shades and use curtains. I can imagine it as being bright and welcoming.

Hello, Here is a color visualizer website that can show you different paint color options: https://www.visualizecolor.com/voc

We have 3” plantation shutters for light and sun control and purely decorative curtains between the sets of windows (six wi Dow’s in three sets of two facing west). We also have a French door on the north aspect of that room that opens onto a careened porch. The door has no shade or covering. Our sunroom is also a regular room, connected To our main living area via three wide arches.

You can get idea of the hanging lights here, they’re going to be repositioned a bit but the reflection on the windows is lovely at night
