It sounds like your underlying concern is how to make better use of the living room area. Removing the wall will give you a greater visual impact of the staircase from the living area but does not necessarily make the living space more usable. You might wish to consider how you are using the living space itself, that is, the furniture arrangement. Perhaps, you might want to consider spreading the furniture out by placing the TV on the left side wall, sofa/ couches in the middle of the room facing each other with a coffee table in the middle....i've attached a rough pencil sketch as an idea....hope this helps...

I have purchased an indigo color 3 seater sofa. See attached pic. I am confused whether i should pair it with a yellow color wing back chair or a printed wing back chair. My living room dinining area is highlighted with a yellow wall. Rest of the furniture in my room is dark tan

So either I can try to hide them or highlight them to look visually, very appealing. Any suggestions/photos would be great! Thanks so much.

ok pls provide me more details
