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

My first question will be: what is the utilities of this room? Who live in it? Age, gender? Is this room oriented by the North or South? East or West? What do you want to feel in this room? Serenety? Concentration? Spirituality? Energy? After all this answer it will be easier to help you. :)

Keep things cool Cooler shades such as grey and blue help walls recede, making the room feel more spacious and light. Bring home the sunshine Light but warm colours such as terracotta or yellow can mimic sunshine and make a space feel bright and airy. Pale ceilings Keep the ceilings in a light colour to make the room appear larger and lighter. While white is your safest bet, you can opt for mint or sage green for a pop of colour.

Hello! I am trying to decide on a color of white for my kitchen cabinets that will not clash with the granite that is already there. I am painting the walls SW agreeable gray and if possible, would like to use the same color white for the cabinets and the trim in the house. This is a North facing room. Would SW Pure White clash with the brown in the granite? Thank you for any advice!
