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 . :)

A combination of Offwhite, Beige Upholstery and dark shades of wood would look good. Provided you keep the wood minimal . The floor can also be a similar shade of wood . Remember whatever you do, make it look rich and elegant, only then will you be able to pull this look off. I am assuming the your ceiling is considerably high as well. Paint the walls and ceiling in offwhite shades with only the feature wall grey

We are located in the Pacific Northwest and want to update our office and shop. Inside our walls are tan with tan tile and the horrendous golden oak doors and trim.

Hey Rahul, You can go with veneer on flush door with brass strips inlayed and do a laminate finish. or if you're looking for something contemporary then i suggest you go for Duco finish with matte finish colors such as white, grey or checkout their shade card for more colors.
