It's looking beautiful to me. Can you explain what do you want?

Are you considering painting that textured material on the wall by the stairs? I would not recommend it. I don't know how paint is going to cover/react with that texture and I believe it's an architectural feature. If you feel like it must be painted, I recommend hiring a professional who can advise you in person, as to what result you might expect, and the formula to use, and to use a professional spraying apparatus rather than a brush or roller. I see that there's a wall light mounted in the middle--I like the idea of using that to highlight the texture, but honestly I would never recommend adding paint to this wall.

I'd go with a gray to match your fireplace. Will unify the two spaces.

I agree. Maybe art would look better. But I’m thinking black if you do paint it

I'd go dark. SW Iron Ore, BM Wrought Iron (any of the warmer, brown toned charcoal or soft blacks)

I think a gray or a white would look more modern. And I would definitely consider removing the adjacent popcorn ceiling. The two textures compete and it pulls away from the wall

Thanks for your input

We want to highlight the wall, to celebrate it. We have large art in other areas of the home so we’re looking for a colour that would bring out the texture. New railings were added and so some of it was damaged we are going to repair it and wanted to paint it as the repairs would stick out otherwise

I think dark charcoal or black like Beth ^^ said. I’d also paint that baseboard the same as the textured wall. It should be one statement floor to ceiling. It’s a really beautiful space.
