We have dark blue canvas that has been on the boat a couple past its prime, but the color still looks good. We are looking at new canvas all around and am thinking of going to "tan" color since we recently painted the freeboard dark blue. BUT we have heard from a couple boaters that the "tan" will fade real fast, even if we went with Sunbrella. What has been your experience with light color canvas? How bad is the staining? the bird crap? mold? dirt in general? Just looking for some opinions before we decide
