If you just want to display information, I agree. Black/White & red/yellow is enough. But if you want to display a photo, you need gray shades.

I know that most people assume that BWY and BWR screens cannot do greys, but that is wrong

Wow. Impressive research and write-up.

"Getting working greyscale turned out to be very very hard. "
