"Existentially speaking, is there such a thing as half a piece of
cake?" --

This evening at dinner the fundamental dynamics of lightsabres came
up. Specifically, how does the color encoding work? Is Luke's
blue because Luke prefers blue, or because any lightsabre Luke uses
will channel Luke-specific force, which is blue? If so, do the
admission criteria at Jedi University include "sabre does not glow
red" (and if not, why not)? Are there important qualitative
difference between blue and green sabres, both of which appear to
channel the light side of the force? Surely these are important
research topics for someone out there who has, you know, seen all the
movies.
