Classic White: White is a timeless and elegant choice for stair banisters. It creates a clean and crisp look, making your staircase stand out. Black or Dark Gray: Dark colors like black or charcoal gray can add a touch of drama and sophistication to your staircase. They create a striking contrast, especially if your walls are light-colored. Natural Wood Stain: Instead of painting, you can opt for a natural wood stain to enhance the beauty of the wood grain on your banister.
