If you do a greyscale conversion and then threshold on a level of grey that is bright enough to be white/dark enough to be black, that's monochrome. https://github.com/ev3go/ev3dev/blob/a5fda5c6a492269e01b184046ed42dc4a1dfe8c9/fb/mono.go#L106-L113 . I don't recall where I got the constants from, but I think they are reasonably commonly used (you could just use the image/color constants).
