Basic physics. The Cyan, Yellow and Magenta is a subtractive system. For ONE of cyan, yellow and magenta the other two pigments have to move to the side of the cell.
Cyan is transparent to blue + green light, blocks red
Yellow is transparent to red + green light, blocks blue
Magenta transparent to red + blue light, blocks green
Thus
red is yellow and magenta layered.
green is cyan and yellow layered.
blue is cyan and magenta layered.
The Cyan, yellow and magenta will be brightest. Red, green and blue will be dimmer.
The main advantage over the mono with stripes is higher resolution. It will still be poor compared to a mono only display for brightness/contrast with no front light on.
Obviously it has 50,000 approx colours rather than 4000 approx on regular filtered eink, because it's not the same cell technology, it must have more than 14 shades of grey, white and black, but this makes it dramatically slow.
While they aim to do a decent screen for a colour ereader this is not it yet.
