I think the kitchen you posted is really cheerful, young and full of energy. Nice retro feeling. It's interesting to compare it with the one below that I just found on Houzz -- which I must admit is closer to what I would choose if I were going green and yellow. But then I'm neither young nor full of energy. I love that there are so many different ways to do things. (I have to admit that in the one below I don't think the blue/turqoise accents work too well.)

Instead of the solid grey, you can go for sketches in grey with flashes of mustard/ yellow. Or, look up these links for wallpaper ideas https://goo.gl/images/OrCtY1 https://goo.gl/images/0ZpAmU

Thanks all, for the suggestion. Yes will stick to white for all other sides of the room. one is full glass with curtains, the other is behind the sofa, a plain wall as of now with no art or anything, this is just opposite to the brick wall. The 4th side is the foyer and a small wall with a artsy clock. The living area is more an open plan, that leads to dining on one side. I am looking for wall art ideas too. I create my own art for the home, I have not gone commercial, just do some art for friends too when they ask as gifts :-). We are changing all the furniture in this room, including the softa. have ordered recliners in light brown color, A square center table with stools underneath, and a side small curio/book shelf. Thanks once again.

Though I voted for the wood panels Its not the always that case it depends upon design to design. To choose any one will be injustice for other design.
