Saber colours in the filmsseemed pretty self explanatory up to and including TPM.
Blue = Padawan/Knight
Green = Master
Red = Sith
I would think Luke's green saber doesn't count, since he had to work with what he had.
Then AOTC came along with Windu's purple. Now since he seems to be the leader of the Jedi Council, yo could say that's why he had that colour. Still, there was rather an equal ratio of blue and green in the arena battle, which seemed to say there were as many masters as knights, which makes no sense.
Then bloody ROTS happened. Now it's completely random whether someone has a blue or green, half the people on the council have blue, half have green. Well done with that Lucas.
So something needs to be done. Everyone having blue will make for a real "holy ****!" moment in ROTJ:R when Luke lights up his green saber, which would be cool, but three films of nothing but blue sabers everywhere with a couple of reds would be a bit monotonous. Have some kind of a system at least, so that the colours are given meaning.
Possibility 1:
Everyone has blue.
Possibility 2:
Everyone on the council has green, as does Qui-Gon, everyone else has blue. Windu has green like the rest.
Possilibity 3:
Everyone has blue, except for Windu, Yoda (if his saber is seen at all) and Dooku, who have either green or purple, and they are set up as the three leaders of the council.
Possilibilty 4:
Kept the same. This is the idiotic option.
Possilibty 5:
Everyone has blue, except for Windu and Dooku, who have purple/green, Windu's role is redone to be that of a borderline renegade, Dooku is redone to be a full blown renegade. This has been done before, and it worked well.
For me, I don't want to lose all the green sabers, particularly Qui-Gon's saber, as I felt it designated him as the master, by having a different saber. However, if everyone on the council has a green saber, since they have to be a master, and to prevent colours being random, you'd have to have Obi-Wan in ROTS with a green, when in ANH, his saber, the same one he has in ROTS, is blue. So really, thanks a bunch for the big mess, George, was it really that hard to keep things organised?
I guess the best way to go is number three for me, even if it means losing Qui-Gon's green. Actually, come to think of it, with option 5, you could give Qui-Gon a green along with Dooku and Windu, since he's already borderline renegade with all his defying the council stuff.
What a mess.
