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

house is good in white. ensure you choose off white colour such as cotton woll and not brilliant white whike repainting. Gate in black. boundary wall in mud colour. overall it would look like a spanish villa. only thing missing is a big olive tree or a palm tree

Greetings From Dream Design, As per your Requirements we are suggestion you some changes -White color -where It is Grey -Dark Cream -Where Blue as it will highlight that area and also well goes with Bricks -and Trims take Dark cream -For Shutters you can also use Cream color So use the White and dark cream with combination as brick part is already dark If you need more help Pls mail us. Thanks Dream Design

The reference image wall color looks like Song of Nature 8401 or Pineview 8400 from Asian. Combine this with Nickel Grey 6126 and you should be good to go. Just paint the recess in accent color and the rest in grey. For getting the sense of color in the actual setup, we suggest you get a big swatch done and look at it in daylight and then in the evening with the warm lights on. The look will change substantially in both cases. You will be able to decide better.
