Blue walls what color carpet?

For blue walls, a neutral-colored carpet like beige, gray, or cream can create a harmonious and calming effect. If you're looking to add some contrast, a deep navy or charcoal carpet can complement the blue walls while adding depth to the room. Additionally, a patterned carpet with hints of blue can tie the elements together beautifully. Ultimately, the choice depends on the mood you want to create and the overall decor of the space.
