Do you mean marble versus porcelaine tile?

16"ft (wide) front and 31"ft back (long)

I am assuming you haven't finalised your wall colours and colours of any other fixed elements. In case you have finalised your color scheme you would need to see which of these colours blend well or complement with that scheme. Assuming none of this info is available, then you could look at the neutrals which go with all colours. The white tile and the 2 colours at the end would be preferable. If you want color on the floor as well as drama, you can choose from the 2nd options from both sides or even the 1st from left.

Hi Jiya, For sure this has gone over the top.. not going into that.. To tone it down we can remove the terracotta red color on the walls . It can be replaced with white color on the brick wall. Window frame color if changed to lighter shades would be great as well. The line where the two floors meet may have to be covered with a uni tone area rug. The sqaure shaped dining bench gives the room a sidey restaurant like feel? Can we not change it . For the curtains and Sofa furnishings , please do not take one with any patterns on it.. uni colored ones with an accent piece would be better.. Thanks, Nitin CORNERSTONE DESIGNS Bangalore.
