Design an ultra-modern and cozy living room inspired by mocha tones, where every element exudes warmth and relaxation. Imagine a minimalist curved sofa upholstered in soft mocha fabric, paired with layered cushions in earthy beige, taupe, and caramel shades. A sleek coffee table with a wooden top sits atop a plush mocha-brown rug. The walls showcase an artistic, wavy gradient in complementary mocha hues, creating depth and a sense of calm. Natural light streams in through tall, black-framed glass windows, highlighting the texture and softness of the decor. Add a potted tree with delicate green foliage to bring life and balance to the rich palette. Use smooth concrete flooring to ground the space and reflect a modern aesthetic. This room should evoke feelings of serenity, sophistication, and indulgence, like a perfect cup of mocha
