Yes and no. Penetrating concrete sealants are designed to prevent moisture from intruding into the concrete, which can cause hairline fractures and cracks over time. It depends on how the color was applied to your concrete. If the concrete has just a topcoat of color, the benefit of penetrating sealant might not be noticeable. If the color is throughout the concrete, commercial concrete sealing can help your concrete structure maintain its steadfastness by keeping moisture out and having minimal cracks.
