Simple DIY hacks for updating neutral living rooms include adding a right-size oversized rug, layering lighting with dimmable floor or table lamps, and swapping small mirrors for larger statement art pieces. For example, replacing a tiny dining mirror with a bold nine by twelve foot rug and larger art instantly grounds the space and adds presence. Incorporate a few planters or meaningful color accents from textiles or wall art for personality. These inexpensive, intentional changes add warmth, scale, and texture without starting over, making neutral rooms feel finished and inviting.
