Just a gut feeling, but not with my money. I wouldn't go with products that have a good chance of being defective. I have heard that the quality of vinal siding varies greatly. You may be able to get top of the line vinal siding in a medium or darker blue. It won't be a midnight blue, but they have stuff darker than power blue. The better products should last for 15 or 20 years before fading becomes a problem.
