Yes, monochrome living rooms can feel warm and inviting when nuanced color shades and textures are layered. Use soft neutrals in different finishes and paints, such as walls and mouldings in the same color but varied sheens. Add contrast with darker elements like a black-trimmed sofa or coffee table to ground the room. Texture from textiles and fluted panels enhances depth, making monochrome minimalist rooms feel calm yet alive and graciously warm.
