Right now they're using separate particles for black and white, with one being positively charged, the other negatively charged, and they apply a charge to the top and bottom of the column the particles are in to cause the two types to move to the top or bottom. When they used 2-color particles, one side had a positive charge, the other a negative charge. I don't know how they'd manipulate particles with more than 2 sides. (I don't think we have that much direct control over quarks yet.

If my memory serves me right gray levels are achieved by partly rotating bi colored particles.
Putting multiple colo(u)rs on the same particle would defeat the whole concept of colo(u)r displaying because each colo(u) has to be dosed grayscale style to work effectively; making this thought next to impractical. An other concept against multiple colo(u)r particles is that if you think at it closely again, when a bicolored particle displays a gray tone it is rotated partly upwards ie. if a colo(u)r particle was there instead, it would show. |

What I meant about cells with different colored particles, btw, was that in one cell there would be white particles and magenta particles, in another white and yellow, in another white and cyan, and in another white and black (the current mode). The cells would be grouped together in blocks, and each block would represent one pixel. You'd need the equivalent of 2x the DPI you want (since DPI is measured linearly), and manufacturing adacent cells with different colored particles would likely not be possible using the current process. But the result would be similar to current 4-color printing on paper.
If the cell method of white particles in black oil were modified, you'd need 4 colors of oil in adjacent cells, which would be at least as difficult, if not more so, than 4 different colors of particles in adjacent cells. Two-sided particles in white and 4 different colors would probably be equally difficult to manufacture. |

And the difficulties attached to color e-ink begin to come into sharp focus.

I'm sure there are ways to manipulate the particles along more axes, but I don't see a way to do it using the top/bottom electrodes in the current generation of e-ink. |

Also each colo(u)r has a thickness to it that will show even at 90 degrees. To be hidden it has to be under, and even then it is not effective enough, this is why our eink screens are kind of grey, the black shows through the particles.
The only practical solution now is smaller more numerous pixels, |

On the more complex shape, 3D intersecting planes, seeing any plane face on means seeing two others edge on, but obviously the edges are thin enough to be negligible (so instead of seeing a solid blue plane, you see on quartered by thin grey, say, lines), or thick enough that they can have a clor, and be colored to match the plane behind them. As abstract geometry, it works. As fiddly electronics, it might require too-fine control, or too-expensive particles and chambers, or something else. That's just reality being disappointing: business as usual. |
