A modern and cozy living room with a cool tone palette. The walls are painted in soft grey-blue, complemented by a light grey fabric sofa adorned with white and pale beige knit blankets and pillows. The floor features a geometric-patterned grey rug, and a light wooden coffee table sits in the center. The room is illuminated by soft natural light from large windows with white sheer curtains, paired with warm white table lamps. Add small potted plants like olive trees or ferns for a touch of life, and abstract black-and-white wall art for sophistication.
