Did you settle on color? Would love to see how it turned out if you have pics you can share! If not, do you have any pictures to get a better idea of what might work for you?

I think that you need mostly white, but something in a print that incorporates your colors. Perhaps pillow slips or at least a mostly pea green painting/poster/wall-hanging that also has some brown, perhaps in the frame. You could also do a stencil on the pink wall using the green paint, some white, and some brown. How about a nice tree branch? You can also buy vinyl decals from Etsy or other places--not sure that you could get pea green, but brown and white should be available.

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

Hi Emran, What a great size room you have. You need to create two sitting areas within the space, and pull them into the room (get them off the wall), also I can see from the fantastic chandelier that you have, that the dining table must stay where it is. I would recommend you go with 3 large area rugs, at least 10x12 looking at the size of your room. I would use traditional rugs with different patterns, yet similar colours so that they all work together. Visit alexanian.com for many rug ideas. They ship throughout Canada and US. Here are some of my suggestions, which I feel will pull together the mustard, red, brown and grey colours. Good luck and I love your space. Wendy
