Yellow, high visibility, works great. Takes about 2 seconds to cover something or take it off. Costs about $15. Check the Arkel website.
(I use the Arkel waterproof cover on my Arkel panniers -- but there is nothing that says you can't use it for other similarly shaped items).
Another vote for Arkel; they make a great product. You can find both rain covers and dry bags on their accessories page:
