Well it depends on your wall color as well . since you have such concrete looking floor I would recommend you can chose any electic color like lemon , orange , yellow to give a bright look and uplift room mood or chose any pastle color of your choice for subtle feel . :)

it's nice but want to improve it a little more.

In moderate budget you can go with vitrified tiles of any brands like RAK, Kajaria,Somany etc they have quiet decent collection and variations suitable for living room. If you are looking at large living room then ,granite also can be option with minimal joints single or two shade combination work well cost would be 150 rs per sft on wards including laying. Italian marble definitely has seamless finish which can add richness to the living room ,cost including laying would start from 350 rs per sft on wards depending on the marble shade grains and thickness purchased. If you are the one who would love to explore new materials then,there are many other options like polished concrete flooring , Epoxy or rustic tile floors etc which is good value add . Important : irrespective of any materials used workmanship makes all the difference. Floating Spaces Bangalore.

You can consider a sparsely printed material for the seat and back but which has traces of the wall colours on a light background.
