Gallery walls are popular. You can do a nice geometric stencil in a metallic. But I'd prefer wallpaper. You can match your paint color to the background so it looks like a stencil, but it's faster and you'll have fewer imperfections. Many patterns come in temporary papers made for renters if you are worried about the removal process.

I gave a pics of my house walls pse gave me suggestions which colour paint best house wall outer and inside the living room.

Hi. 1. Install hydraulics on existing shelving. But before installing that go for a washable paint. Kitchens get dirty daily and you can clean the inside easily. They will cost you less and you will have maximum space. 2. Install few rods to hang in your essentials. 3. Get a pantry section done. 4. Use vertical arrangements for cabinets so that your kitchen stuff stays inside giving a cool look on the outside. 5.If possible get a sink done in utility area so your kitchen is always tidy. 6. Try not to waste your space in the kitchen in case you have the utility area near to kitchen just by providing lpg storage in utility area. 7. Paint colours of walls, Tiles and laminates of cabinets/shutters should be contrasting each other to give a good look.

I think you can opt for yellow, TV areas..... but do circle the door... DB area wall paper would be a good idea...
