Clever idea. But you'll still need at least three layers, and some way of
defining and addressing individual pixels.

Or you're going to have to shove a shitload of electrodes into some poor
cuttlefish.

I'm not sure I'd want a cuttlefish near my face while making a cell call.

i'm waiting for someone to make paint containing cuttlefish pigment - you
could have a colour changing car.

If you frightened it, you might end up with a face full of ink.

I can see the ad campaign now: "The newest thing in 4G--the CuttleCall.
It's cuttle-edge. It's exciting! It's *dangerous*! Use with caution."

LOL. Yeah, that's probably exactly how they'd market it.

One great advantage would be that it could stick itself to your face
instead of you having to hold it to your ear.

How does one get magenta (red + blue) to show? Since the cuttlefish
panel material can match any single wavelength (colors from the rainbow),
but other colors are out of the question.

Pixels, same as on an LCD.

Except you're talking about a dithered color scheme; don't LCDs (and
practically anything else w/pixels) allow pixels of any arbitrary color,
not just intensities of R, G or B?

No, the pixels are combinations of R G B as there are three fixed color
filters.

If you are going to do pixels combining the primary colors, you might
as you do fixed color filters and you don't need the cuttlefish
inspired color changing filter.

Yes, that's what I meant.

Hell no! It's RGB all the way.

Don't LCDs (and practically anything else w/pixels) allow pixels
of any arbitrary color, not just intensities of R, G or B?

It's the varying R/G/B intensities that create the "arbitrary" colors.

Note that you can't create colors with greater saturation than the
saturation of the primaries.
