Flooring upgrades like luxury vinyl plank (LVP) or peel-and-stick tiles work best over brown tile floors when paired with green countertops. These options provide a fresh, modern look without fully removing existing tiles, and they help neutralize the undertones causing clashes. Choosing a flooring color that mimics warm wood tones creates a calming, intentional backdrop that enhances green countertops and complements existing cabinets beautifully.
