One colour filtering plan is to have groups of four sub-pixels, one of which is without any filtering, and the others are Red, Green and Blue.
If the base ClearInk white has twice the reflectance of E-Ink white, then the ClearInk colour display white will have around the same reflectance as E-Ink.
Assume that the colour filters let through 1/3 of the incident light. Then the total light reflected by the three coloured sub pixels is equivalent to the reflected light from one white sub-pixel, so the four sub-pixels in a colour display reflect half as much light as four 'sub-pixels' in a B&W display.
So the white subpixel is twice as reflective as E-Ink, but the colour filter cuts reflectance in half. So the 'white' of the colour display will be about as white as an unlit E-Ink display.
It sounds promising. But so did Liquavista.
