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

Manpreet, Congratulations on your new home! You can go with BWP ply with laminates. You are right in your choice of matt and glossy laminates for base and wall cabinets respectively. Without knowing your tastes, I am taking a chance to suggest you 14541 for base and 21187 MR+ from merino catalog. It looks good. 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...

Greetings from Dream Design, -Oil based paints can actually be toxic, and has strong fumes -Acrylic paints are among the most popular type of paints on the market. Water based, they are also the easiest to clean -Latex paint is water based, but differs from acrylic. Latex paint is also easy to clean This paints do not do well with faux finishes or any type of glaze. So overall Acrylic Paint is best paint
