Hi Yashika, what room are you wanting help with? Do you want ideas for color or room arrangement?

Could you post a picture please?

I would use the greens from your bedspread. Since you have green in the bedspread, and brown and white tiles, those 3 colors need to be your focal point. So I have painted your wall a bright olive green ( the darker color in your bed spread) and the ceiling either a brown to match the tile or a white to match the rest of your ceiling. then or I think this last one is a little tamer . But you should be able to paint over the tile. WHAT kind of tile is it? If it is ceramic you can paint it. Here is a link about how to do it: https://www.sherwin-williams.com/property-facility-managers/education/styles-and-techniques/sw-article-pro-resuscitateold.html

Hi not clear about furniture color combination...we have to think about over all color combination... if you like grey color go with lighter shade like Gentle grey...here attaching some reference images take one combination.
