We prefer the grey colour over the old brown one. 
Installation and removal tip: The cover will seem too tight to fit over the far end posts unless you raise it at the 2 posts where you started from. It's real easy with 2 people working 1 at each end.  Same for removal. You need to raise the cover on opposite corners until it's lifted over 2 of the 4 posts, then it lifts off easy.
