I don't suppose any of the cladding or other metal work is being created as a bespoke product. It's probably all off the shelf so to speak isn't it? In which case maybe it only comes off the shelf in RAL 6007 and that RAL 6005 would require a bespoke product that would cost more. If so it would follow that the club would then paint the facade and other areas with the same colour. Just a thought.
