IMO, you need an off-white with a faint yellow undertone. Your inspiration photo above has a white wall, but is reflecting the coral, making it look warm.

I found this photo of a room that appears to be without natural light, and it is a good example of what the walls will look like with lamps on…as they will be.

This is B.M. OC-112: Goldtone. Works very well in low light North facing rooms, so it will work for your office.

Not sure I love the coral chair/desk with your floors.

Unfortunately, there is no crisp white that will look good in a room that gets very little natural light. To be successful, white needs light and a lot of it. Better to take a look in the off-white family if you are set on a light colour. Something like BM OC-9 Ballet white which is creamy and very neutral.

The other big thing to consider is lighting. Overhead fixtures mostly create gloom. Use a mixture of task and ambient lighting with lamps and if your want to throw more light around, use that old tried and true trick of placing mirrors near light source to reflect extra light into the room.

Good luck with your project!

How about also painting the fence outside the window to reflect more light into the room?

Prime it white with KILZ or Zinzer and change the lighting to better LEDs in the 4-5K range before you try to pick whites for this room. You'll have to take into account your white baseboards and heat units. Here is a nice combo believed to be Navajo White walls and White Dove trim.

Thank you all so much - you mostly confirmed what I suspected, that with limited light, it may be better to improve the lighting and go into off-whites. I also think that the idea to paint the fence outside white is really creative and may help bounce some light into the room.

I'm very grateful for all your comments.
