This pattern? https://commons.wikimedia.org/wiki/File:ConeMosaics.jpg https://commons.wikimedia.org/wiki/File:ConeMosaics.jpg Maybe we should put the electronics in a layer in front of the display, make them transparent, and use them to filter the light. The vertebrate retina does something like that, putting nerves in front of light sensors. Imitating evolved solutions isn't always a good idea. Nature's design process is like: start with the wrong parts for the job. Lay them out back to front. Wire them together the long way round. Adapt this design slightly and latch on to any convenient side effects. Iterate ten billion times. Now it works pretty good! Or it doesn't, but the species survives anyway, which is also fine since there is no goal.
