Did you settle on color? Would love to see how it turned out if you have pics you can share! If not, do you have any pictures to get a better idea of what might work for you?

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

Hi,  An oversized painting / wall mural / traditional wall art (you may choose state specific on this one) should highlight the volume and height of the space. Additionally, good lighting - wall scones / chandelier will add to the beauty. Hope these tips help!  Regards Ar. Manjusha Adhav - Kamble
