To complement black and white curtains and a brown and cream carpet, consider painting the walls a soft, warm beige or light gray. These colors will create a neutral backdrop that harmonizes with the curtain pattern while enhancing the warmth of the brown carpet. For the couch, a deep charcoal or a rich chocolate brown would work well, providing contrast without clashing with the existing elements. Adding accent pillows in cream or muted colors can further tie the room together.
There are several approaches you can use. You can use another shade of yellow or brown. Or you can use a neighboring color on the color wheel and use orange or green. Or you can go for a contrasting color, and purple would be good for that.
