Dudes, that is a stock image from Dear Kids. That is not the person's room. Dear poster, It would help a lot if you showed readers the colour of the floor, trims, other furniture and even the ceiling. Too, it would be good to know what style of house you have and the other colours in your house. Why people who reply go to more bother than the person who asks the original question, I do not know.

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

go for monochrome black and white paintings. it will look stunning!

Karthik, Interesting. Not sure who would have advised you to get these tiles. Usually, these are meant for bathrooms and swimming pools. Let us get back to you on suggestions to work around this one. Thanks, Nitin CORNERSTONE DESIGNS Bangalore.
