Greetings,
No, the color panel on this dishwasher model is not interchangeable with other colors after the initial purchase. The unit is designed with a specific solid white glass finish that is not meant to be field-swapped like the panels on some other Samsung Bespoke appliances (such as certain refrigerators). The Bespoke feature for this specific dishwasher model refers to the color options available at the time of purchase (e.g., White Glass, Stainless Steel, Matte Black), not the ability to change the panel later. If you desire a different color, you would need to purchase a different model or an entirely new unit in the desired finish.
Have a great day!
