I've always wondered about the use of colour 16 in stickers - unlike bricks, there's no such thing as a "sticker that comes in multiple colours", so I'd have thought we would want to model the sticker exactly as-is - with either colour 15 for white stickers or something like my proposed colour above for transparent ones (and other colours if/as required, of course).
