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

Hello Meghna, Do you have any pics of the room. Please let us know your preferred shades. Thanks, Nitin CORNERSTONE DESIGNS Bangalore

mostly Indians uses brown varnish paints for their main wooden doors....I even don't know why they didn't use other colors...even in my house doors are given brown color wooden texture...

Harin, Veneer is a possible option , you can get it polished or laminated. It will require a bit more attention than other finishes when maintenance is concerned. DUCO is a soft finish it looks great and can be done but it's not scratch proof so care is required.Even if scratched you can get it repainted after few years.
