What are the different grades of corian?

Corian doesn't have grades in the same way some other materials might (like lumber with different grades based on knot density). There's no "Corian Grade A" versus "Corian Grade B."

Instead, Corian offers a vast range of colors and patterns. These are the distinctions consumers typically encounter when choosing Corian. Some colors might be more popular and therefore more readily available, but this isn't a formal grading system. The material itself maintains a consistent level of quality across its color range.
