I would do Lulworth or Dix IMO the other choices are too dark for the space

They are both nice, but I think too dark for that room. I agree with Patricia,,the Lulworth is beautiful. I've seen it in a small office and it looked really nice

thank you for your comments - really appreciate it! If you had free reign with the colour palette would you consider any other colours (other than blue)? I love all the F&B greys but not sure they would work in this space.

I'm of the school that thinks small rooms can be great done in deeper colors. Our den is in a blue between Navy and Royal and it's beautiful. I think Inchyra Blue could be lovely for your space, although you may want to change your carpet. I love Farrow and Ball's color names—we are about to paint our living room Mouse's Back.

Mouse's back is a gorgeous colour - I love the subtle green hue to it in certain light

Yes, we are excited to have found Mouse's Back. It picks up the color that is in a couple paintings we have in the room and should set them off nicely. F&B's colors are wonderfully complex and nuanced.

I think it might depend on the color of your furniture.....is that white leather you are using? If so, the darker colors might work. However, I recently changed my watermelon walls for a cool blue green. Sofa and larger chairs are black leather. It's a small beach cottage and the lighter color makes the rooms appear larger.

One of my faves is String it has this ability to change color with the light and I find it facinating

Alice, I love your new colour, it makes the space seem much larger! Yes we will be keeping the white leather furniture (it has a touch of blush pink in it but really subtle). I think I should have cleared out the room before I took and posted photos, would have given you a much better idea!

I like F&B Parma gray

A belated response to say thanks to those of you who told me to go for it with a dark Colour. We picked Farrow and Balls Moles breath. I love it!!!! Getting the right artwork definitely helped.

looks lovely and that painting really brightens up the room
