The B&W capsules themselves are opaque since both pigmented particles are in the same capsule and the bottom electrode is also opaque. The Gallery colour cups add cyan, magenta, yellow particles and lose the black particles but are equally opaque. Oddly, you can get a eInk film for tinting windows where there are only black particles which move to the side to allow light through.

So you are seeing light reflecting off the particles pretty much like light reflecting off paper.
