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 . :)

I have a 30x40 east facing plot 40 ft east to west and 30 ft north to south,want to build a duplex with one bhk at ground floor and a car parking.need help to get floor plan.

White and same wood colour is Good colour combination

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