To update a kitchen on a budget with brown floors and green countertops, focus on small swaps like adding a neutral runner, swapping cabinet hardware for sleek black pulls, cleaning or updating the backsplash, and improving lighting. These simple tweaks bring harmony and calm without the cost and hassle of repainting cabinets or replacing major surfaces. Over time, you can save for bigger upgrades like flooring or backsplash replacements to continue enhancing the space.
