Or do 16 throws of such a d(2) die, i.e. 16 coin flips, in succession. If you really want to do it in one throw, you don't really need to color them all differently, though. Just read them in a specified way, i.e. always from left to right and top to bottom. (You don't even have to always read them the same way as long as how you read them is completely independent from what their faces show.)
