Wall color depends on the color of your furniture, cabinets, counters, backsplash, etc. post photos of your stuff.

You should really think about the following things when choosing paint colors.

1. Lighting - How much natural light do you get? Do you get lots of natural light during the day or is it dark? Also, for at night time, what color light bulbs do you use? Warm White, Bright White or Daylight? This can determine what colors you should avoid. Artificial lighting can also change how a color will look.

2. How expansive is the room? - Do you have a large space with soaring ceilings or is it a basic room with typical 8ft ceilings? Going dark in small spaces can make it seems like its enclosing in on you making the room appear smaller.

3. Hard Surfaces - I try not to base colors on furniture since those items can easily be changed out though out time. I try to look at things that are costly to replace or will not ever be replaced such as fireplaces, hardwoods/tile flooring, counter tops etc. Since those items are usually not replaced it is best to work with them in your design.

Hope that this helps you choose the right colors.

PS. My go to gray colors are SW Repose - SW Mindful Gray - SW Agreeable Gray
