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.

Hi Murugesh, Use a subtle difference in the tile you are using. For example, if your walls are charcoal grey, use a lighter grey tile on the counter or the floor. If your room is painted brown, consider a lighter beige tile. Stick to neutral colors to avoid a mistake, you can't go wrong. Best of luck!

Fantastic....I did the same with a big dark cabinet....painted it a cottage green and now get soooo many compliments.

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
