If you want to highlight the staircase wall then your could use earthy colours such as a yellow ochre! The wall could be enhanced even more by using suitable frames and making a good collage composition for all the photos that you have (I can see many lying on the dining table). This colour would match well with wooden furnitures

Definitely YES!

Thank you Shalaka ! I do love it the way it is but since the windowstart are ceiling to floor and facing West, in summers it becomes a furnace. Hence the need for double curtains. So wanted to get something that when needed if I tie the front cream ones from the back when they show, it looks nice. While my husband liked orange, I was leaning towards, gold. So we decided to put it for vote. Thank you for your input :-)

you can go with brown, light grey, black with curtain I think so it is good and create a natural colour palate
