What Is the Best Trim Color to Use With Green Onyx SW 9128?

White is typically the most widely used trim color due to its versatility and ability to pair with almost any color on the walls.

Use SW High Reflective White if you need a crisp and stark contrast, and opt for SW Shell White for a softer and warmer appearance.
