See the kernel code already supports 4bpp - 16 color, which gets squashed to 2 color, then to 1 color, but with PWM grey scale. But the application doesn't mean to write it in color, jsut grey scale. So I could give you from black to [insert your favorite color here], rotate thgouhg colors and such, but the entire display woul dbe shades of one color. As far as I know the "application" is not open source... adn that would give us a really cool display!
