The Rochelle sofa in Hydra is my absolute favorite. I'd design a whole space around that thing! It's got such a great pop of color I'm not sure you'd want too much going on with the walls. Maybe a silvery-gray?

I love the idea of keeping a cool green color story to your whole wall color scheme. I think that the green would be great for the computer room. I would do a less saturated green for your main room. This would tie nicely to your couch and would accent your floors that you just spent so much of an effort on.

I'm a sucker for Benjamin Moore's Veil Cream, which i think would work great with your sofa....

I'm a fan of silvery-gray, too! White accents would just pop and keep the whole colour scheme fresh and clean.

Too open-ended a question, with too few style clues, to answer.

I love cool, pale silvery grays as well. It compliments the sofa while still being neutral enough to add in pops of color in your accessories.

Paint makes SUCH a difference-totally completes a space.

If you are going for a brown, I would suggest a minky brown instead of a chocolate, per se. (Cobble brown or one of the tones on the same colour strip from Sherwin-Williams is beautiful) and if you are looking for the perfect celery green, Lemongrass from Benjamine Moore is lovely in most lighting-and wouldn't be too bluey-green when co-ordinating with your beautiful blue sofa in the next space.

A lovely lighter choice would be an old Sherwin-Williams colour called "Thatched Straw"-it picks up beautiful tones in all different types of light. (Its a buttery, yet very neutral greyed down yellow)

Thanks to everyone for their great comments. After considering a deep brown accent wall, I think I prefer the cool, clean feel of a silver-gray color for the living room and BM celery in the computer room!

I'll be sure to post follow-up photos!
