Hmm. I guess since it is a reflective display when the pixel is dark then it reflects so little light that you can't see the filter at all.
The specs seem to be the same except the reflectivity is slightly different and the refresh time is also different.
The change in refresh time is massive though! 120ms for mono vs 240-980ms for colour. Thats a heck of a jump! Worst case would be nearly a second for a colour page refresh which is going to be painful and even best case is double what the existing mono screen can do.
