Can you post a picture of the adjoining areas so that we can see your style? It would help to make suggestions.

There is no furniture at the moment, there will be a charcoal grey contemporary style sofa with a black Ikea Lack TV console but I haven't bought anything else yet

First, I would suggest picking a second color to go with the green. Some options could include wood tones/leather/brown, navy blue, or maybe a light blue. I personally would lean the brown/brown wood/brown leather and then let that color and the green lead your design.

I might try brown leather dining chairs or brown wood with a jute rug underneath the table. Moss wall art is a cool idea, maybe it can have a brown wood frame. You could even go pretty large with that, and if you want to save money, it's not too difficult to do it yourself. You can order moss off Amazon or Michaels, and can even get in different shades of green to bring in a 2 tone green effect. There are leather/wood/carved wood art out there - check out Etsy for ideas. Depending on your location, you could get art that ties in those colors with your geographic location (for instance, if AZ, then Cacti, etc).

You can find green ceiling/sconce/table lamps. Here's some examples - expensive site but can give you ideas. If you like one of them, do a Google search on the image and you can find similar for cheaper: https://www.schoolhouse.com/collections/all-lighting?filters%5Bcolor%5D%5B0%5D=Juniper&offset=24

Love these chairs with the black legs and wood tone. You could continue on with the style in the living room.

I am an Edward Hopper fan:

Edward Hopper Gas, 1940

Born and lived in Greenwich Village, he spent every summer on Cape Cod he spent summers on Cape Cod and built a house in South Truro in 1934).

This is my neck of the woods.

Here's one idea...

@B Lyons: great ideas about adding another colour to the palette, I'll definitely look into this.

@lisedv: how did you create that out of curiosity? I like what you've done with it.

Here's what it would look like with some moss wall art I found online:

I do it all in PowerPoint.

Your moss art is interesting and goes well with your decor but you placed it much too high on the wall.

What would be the rule for wall art placement generally?

I like it not too high. If you have space, you can place a long console or floating shelf under your moss art that serves as a buffet.

A good rule of thumb is to hang art so that its midpoint is between 57 and 60 inches from the floor. Aim for the lower end of the range if most members of your household are on the short side; in rooms with ceilings higher than eight feet, artwork can be hung a little higher than 60 inches off the floor.

Wait - wasn't there a post about this same table not too long ago? I do recall replying to it with a suggestion of black Windsor-style chairs...
