People here usuallly choose light colours but i wanna try something attractive....like something new to them..Please help me because My sister's wedding is coming. :)

I think grays and blues would look great! here are a few accents that may go with your yellow color. I also think that if there are a few pops of bright yellow you would be ok! http://deciture.com/antique-styled-floral-wood-metal-wall-decor-3-assorted/ http://deciture.com/artistic-styled-metal-wall-decor-assorted/ http://deciture.com/attractive-styled-metal-flower-wall-decor/ http://deciture.com/peacock-in-print-wall-decor/

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

Depends on what effect overall you want -- hot tropical feel (oranges and reds) or a bit more toned down? You can take inspiration from pictures of gardens with lime green heuchera or sweet potato -- often paired with chocolatey purple, silvery greens and blues.
