I like the three you posted together, but I’d remove the one already on the wall. That one doesn’t blend.

Creamy by Sherwin Williams will look great in there. It’s a nice cream that doesn’t read yellow. Or you can go with a white (extra White by SW or Chantilly Lace by BM). Sample it first, though. Buy a small sample and paint a large piece of foam core or Sheetrock, so you can move it around the room.

Draw the room to scale and also the furniture you plan to the same scale then see if it all works. I do not like guest room s in my office but that is me. What you show and what you describe are not the same. I guess a sofa bed but this in not a big space so planning is a must. if you want guests in there too . How fsr from a bathroom is this space ? Maybe just forget the guest part and design for your use only then 2 choirs the desk and a TV with some maybe a Sapien book shelf for an empty corner to make the best of the space . Also do you need storage for th office equipment ?

Just came across this room and I love it, seems to serve a similar purpose as ours! Wondering if I should be looking for mirrored coffee tables? Hmmm... not sure how comfortable those would be. Any thoughts?
