What color comforter should I get?

You can go with a white comforter with a black or grey pattern for a sleek modern look or you could add some colour to the room with a comforter or duvet cover in your fave colour. Any colour would look fabulous with the neutral black, grey and white decor you have now.

I'd get a solid colour reversible one so if it's red on one side and black on the other side, you could change up the look of the room just by flipping the comforter over.

yellow red

A white comforter would compliment the colors

You need a pop of color, red, yellow or teal, or purple would work.
