I would do gray walls and just make sure it has the same undertone as the tile I often paint the ceiling the same as the walls if going with a light color or if a little darker for walls I cut wall color 50% for the ceiling. I have a gray and mostly white LR and I have walls a color called Vancouver Day from C2 I then add color for different times of the year with pillows and a few accessories The wall behind the sofas I just painted in a purple from one of the pieces of art and I love it.

Have you considered a mural? We make a durable, non-fading material that is seamless up to 5 metres wide on the short side (length can be over 100 metres!). Normally we install it on ceilings, so it is called 'stretch ceiling', but it works just as well on walls, and can be wide-format printed with any high resolution image. A narrow, nearly invisible frame of aluminum supports the material all around the perimeter. Our material also comes in translucent, which we can install with LED lighting behind. Here are some previous installations of ours. Please feel free to browse our profile and add anything that inspires you to your ideabooks! The material and framing is all fully recyclable.

Pista green color looks good. I was actually looking whether we can make something to contrast the blue glass windows.

Priyanka, Wallpaper on doors is not a good idea. You can go for laminate panelling on the wall and matching laminates on the doors. You can choose a veneer as well. The space is too wide for a single door though. You will have to plan accordingly. I am assuming you are talking about the brown door and not the other black door in picture.
