We just painted our walls agreeable gray to match the kitchen island. The cabinets are alabaster white. I love the contrast especially in high ceilings and the angles. the agreeable gray is very sublte. Every wall shows it in a different view depending on the lighting. I'm pleased with it.

Think about how your lighting will function in the space, then consider the ceiling. I’d start with the entry and go from there: Do you want light directly above/on top of your guests heads as soon as they enter? With your furniture placement, will lights highlight art and walking areas or shine down onto people’s faces and laps as they sit? A good recessed lighting plan adds dimension and sparkle. A disappointing one casts gobs of light (and shadow) in all the wrong places. Try visualizing the dark but finished space, then add each can and picture the light and shadow as you go. When the rooms looks good, look at the ceiling and adjust. The lights don’t need to line up as if they’re on a whole-house grid.

IMO wait until you are in the space before buying anything Take some pics of the space and the sofa post a to scale floor plan and then you will get some real help.As for TV check out Besta from IKea make sure the unit is low enough so the middle of the TV screen is at eyelevel when you are seated if you have the space you can but this system and its pieces together to get a real custom look. BTW I love the Eames chir and ottoman with that style and color of sofa

Okay - did the corrections and think I have a close approximation of your space. Each block represents 1 foot. The gray area is the space needed around the island for walking with people seated - should be clear of furniture. Can you take a picture of the full wall where the fireplace and tv nook are - not sure I got their placements right. Do you plan on using the tv nook for the TV? How did you envision the living/seating areas when you designed the kitchen? How many people need to be seated - do you need a dining space and how many people need to sit at the dining table or are you just using the island for meals?
