It's not the color of your lightsaber that matter

Actually I think it makes sence with only green, blue and red. And I guess there are some purple crystals as well, in the real universe there are, very rear but it excists.

I can't believe for a minute that blue, green and red are the only colours. We've seena white blade, although it may have just been a very pale blue.

Also, I expect to see Sam Jackson sporting a purple blade. If they restrict the colours like that it will make the saber battles very boring, I was really looking forward to a mass Jedi battle with many different blade colours flashing about.

where have we seen white Ratcat?

the very first toy lightsabers were white, I don't know if that counts, but wasn't the original design for lightsabers gonna be white?? Finti, why does it make sense to have three colors, all the jewels are rare, and come in various colors

You listed the reasons yourself and think about it. It actually fits what we have seen so far. I know crystals are rare, but some more than others.

I see.. and what exaclty does it "fit" Finti??

Hey, Merc! You looked at the crazy site! You guys should be careful what you say about crystals. The guy who runs that site has very high and mighty opinions about THEM as well...

Mind you, he does make some good points, like the fact that Lightsabres cannot be anything to do with 'light' at all because they cast a shadow...

Anakin calls it a lasersword as well. Laser is light.

Well, I would imagine he calls it a Lasersword in the same way that everyone else calls it a lightsabre- becuase that's what it looks like (quite why GL chose not to use the word 'lightsabre' in the entire of TPM is beyond me, however), but the evidence (like the shadows, and that it doesn't seem to emanate heat) is very much against it. Not that you want to get TOO technical on such a fantasy notion, of course...

As for the colours, certainly there seems no consistent logical reason that anyone can come up with to explain what they mean. That in mind, quite why there should be only three colours is beyond me, but that does seem to be the way the wind is blowing.

Someone's going to question my comment about it not emanating heat now, aren't they? I assure you it's true.

ehh, good point Ushgrak, I..guess. Since there has actually been 3 video games with different colored lightsabers, I don't think GL would want to confuse the fans(unless of course, he is a heartless S.O.B.).

Okay...I'm confused..where did it say that they don't generate heat?...and what's all this about they're not light because they cast a shadow?...The Sun casts shadows, so why can't a lightsaber?

right on DIM!!

BUt the sun doesn't cast a shadow of itself. But if you stuck a BIGGER sun behind it then it would. So maybe the ambient light is defracted by the baldes containment and therefore you get a shadow.

As to the White blades. Wasn't Lukes original sabre (Anakins old one) white? Or was it a very pale blue?

I could have sworn it was pale blue

Several things:

First of all read The Science of Star Wars, it explains why a lightsaber is not really light, but probably plasma.

Gems of all kinds can be used. The most common are Adegan crystals and Corusca gems, but diamonds and even pearls have been used.

There has already been a purple lightsaber(Gantoris & then Kyp) and a yellow one(Leia). So if it is true that there are only three colors then continuity will be thrown off.

And George Lucas is a heartless S.0.B. He will through off continuity whenever possible. He doesn't care what happened in the novels, he will just contradict it.

I'm starting not to like GL for any other reason besides his movies, has he actually done anything good besides that?? Anyways, this all goes back to a discovery I made while I was a freshman in high school, I had just gotten off the bus, it was a warm day, the sun was out, I was carrying an empty mountain dew bottle, when I looked down and noticed that the shadow the green bottle was casting was green!! I was amazed at this, I don't know if this does anything for this topic.

Ok, I will now defend myself (with canonical sources, at that).

The lightsabre itself has s shadow, cast in the normal way from other light sources. Therefore, no matter what, it MUST be a solid object, and therefore cannot be light or laser or any energy form like that at all.

Supplementary evidence for it being a physical object- because it ACTS like one! Best example I can give is Qui-Gon, who is clearly IMPALED on Maul's sabre. If the sabre had no phsycial presence, Qui-Gon would have simply and messily fallen through it when Maul stabbed him.

As for the heat... anything that generates enough heat to melt a bulkhead would do far more than the sabres do. For eaxample, the snow on Hoth should have been melting around Han and Luke when they turned on their sabres their. Further more, Qui-Gon's clothing should have caught fire when he was impaled.

Now... I could explain how the sabre PROBABLY works, based on what we've seen (explaining why exactly the door melts if the sabre doesn't produce heat... it's perfectly consistent in scientific models, just look at microwaves...) but it really does get tiresome after a while.

what were you defending yourself from Ushgrak??

Those people who wanted to know what I meant by no heat, and so on. Perhaps I should have said 'explain'

why do you keep saying canonical??
