So, I just started decorating my livingroom in my new apartment. I got the sofa and vittsjö table. I will have two barstools in the blue patterned fabric facing the kitchen but still will be standing in the living room, The legs of the stools will be brown as the feet on the sofa.

Im finding it really hard to decide on color scheme. Its a small place therefore I bought the table in metal and glass, now Im considering buying the tv stand in the same style aswell, will it be too much?
Should I try to find something in wood to match the barstools legs.?

And what about the empty space in the corner?
Above the couch?
Oh and a rug?

What avbout having a mustard yellow as accent color? To bring som warmth back?

Please help me!
