A filter causes attenuation on displays which are already not of coal on snow contrast.
I am convinced that next is colour, but I bet on the ACEP, the "Advanced Color ePaper" - having in a single dot (cell, pixel) the pigments (like Cyan, Magenta, Yellow, blacK) required for subtractive colour synthesis. Of course, we have to wait for it to became a viable mass production possibility.
The text remains hi-res because the filters multiply on black (dark grey), but applied on the whitey background the filter should make it become a darker net of coloured spots - your background, normally white but now under a grid of Red-Green-Blue-Transparent inks, would become a mixture of colours... It works with lights (R+G+B = W), but it is not natural with inks.
You need, as you have now, elements that go White-to-Cyan, White-to-Magenta, White-to-Yellow, White-to-Black, and possibly in the same cell. This simulates print. Advanced Color ePaper is implemented around this.

Having only 8 colors is a big drawback for this technology. 150 ppi is the resolution and it will soon also be the resolution of of Triton with color. LCD displays are also based on filters. I understand how the higher resolution text works and while white does need all the colors I think it seems white enough for reading purposes. These days frontlights tend to dictate the white color anyway for many users. Besides there is nothing that says the colors have to be true red, green, and blue, they can be altered slightly as you already suggest. There could be a mix of mutiple colors and filters using something from both technologies.
