Re: Communicating colour to aliens

If I say part of the spectrum, would that be more acceptable?

If one wanted to contunue and split hairs on this, one could say that 30
points along the spectrum does not capture the spectrum or even 400 points
because the spectrum is continuous. So all these methods capture parts of
the spectrum with different levels of accuracy. 

I totally agree with your point, three points or three zones does not
accurately describe the spectrum.
