• but how can I show some shade of grey? Is that not possible?

    Not without dithering - because of the 3 bits.

    On Bangle.js 2 you may not even need the separate buffer. In fact I just pushed an update to the development app loader which renders fullscreen, and direct.

    Bangle.js 2's graphics aren't super fast at the moment (particularly the fill) - it's something I've been meaning to look at. Specifically if we were willing to throw away a bit of RAM (aligning to 4 bits, not 3) things get a lot easier!
