USN life raft color mid-1950s?

Most pics I've seen they look gray to me to match the hull, ie blend in from the side against the superstructure.. But I'm no expert.

Also, for those about to respond, what abt the canvas covers on boats stored on deck?

I just happened to be watching "The Bridges at Toko-Ri", which is a gold mine of mid-fifties naval ships and aircraft, all in brilliant technicolor.  In 1954, the rafts on Oriskany, the carrier used in the film, appear to be a slightly darker gray than the haze gray color of the ship itself, but nowhere near black.  Obviously determining exact colors from a fifty year old film seen on a television is impossible, but if you called the ship "light gray" then the rafts would be "medium gray".  The canvas dodgers covering some of the railings on one of the accompanying destroyers  were a much darker gray than the life rafts.
