Saga General Theory of Lightsaber Color

Hey, new here.
Not sure if this is the right board to post, but stick with me and tell me what you think of this theory.

[SPOILERS: Star Wars-Ahsoka novel; The Clone Wars; Rebels]

By Disney's new canon, kyber crystals are all white now and able to cast any color saber, depending just on the user's relationship with the Force.
If the user imposes their will onto the Force and fills the crystal with the dark side, as a regular Sith would, the crystal "bleeds" and turns red, as it's told in Ahsoka's new book. If the user submits to the light side and supresses their feelings, the crystal casts either green or blue sabers.
Even though we don't have canon explanation for the meaning of blue or green sabers, it is apparent that, in general, more visionary Jedi and of greater force knowledge carry green sabers, such as Yoda and Qui Gon, while more proactive and physical Jedi carry blue, such as Obi Wan and Anakin.
Still, I haven't found other explanations for other colors also present in the canon universe, such as purple, yellow, black, white, yellow-green and light-blue. But I believe they can be explained by simple additive logic.
The thing about white, black and purple is that those colors never show in the visible spectrum of light. Purple, for instance, can only be composed by the mixing of blue and red, which are at opposite ends of the spectrum, which means Mace Windu's saber necessarily casts both blue and red light. That fact corroborates the popular theory that Windu uses both light and dark sides of the Force, although that is not confirmed in canon.
By the same reasoning, though, should we assume that Temple Guards' yellow sabers are actually mixing red and green? Yellow is actually present in the visible spectrum of light, but mixing red and green still makes yellow, since we only see yellow light because it stimulates both the red and green sensitive cells in our retinas.
Assuming this idea, Temple Guards then use the dark side like Windu, never totally imposing their will onto the Force and being more focused on knowledge of the Force than physical abilities, while Windu focuses more on the physical.
It is still a possibility that yellow sabers simply cast pure yellow light instead of mixing red and green, but if that's the case, then we have no explanation for the fact that they're neither blue or green. Whereas if we assume it does cast red and green light, we can explain it just like we explain Windu's purple saber.
In canon, we have also seen Ahsoka's yellow-green saber, Tera Sinube's light-blue saber (which is awkwardly white), hinting that saber colors might be able to mix indefinitely, depending only on the user's relationship with the Force (at the moment they meditate with the crystal to assemble the lightsaber, most likely), even though there are great tendencies toward blue and green.
Could we say then, that a Jedi maintaining perfect balance between mental and physical abilities, without using the dark side, could create a cyan saber (not yet seen in canon)?
Yellow-green and light-blue sabers could be explained by the same logic, signifying a greater balance of abilities and moderate use of the dark side. That leads us to black and white colors, which have only been seen in Ahsoka's new sabers in Rebels and in the Darksaber, in both series.
Neither black nor white are colors present in the visible spectrum of light. Instead, white is the mix of every color, whereas black is the absence of light in the visible spectrum. White, though, can be made visible by mixing just red, green and blue, the primary colors our retina perceives. Because of this, it's just obvious that white sabers are casting at least those three colors. And it raises two possible interpretations.
The first being that Ahsoka now uses both light and dark sides of the Force, while maintaining perfect balance between her mental and physical abilities, so as not to decay to purple or yellow sabers.
The second interpretation, which is way more reliable than the first, would be that red sabers are only revertible to white. That could be the case, since it was by retrieving the kyber crystals off of the Sixth Brother's red lightsaber that Ahsoka made her white lightsabers, instead of them just turning out green like her previous lightsabers.
And then there's the Darksaber mistery, about which I don't have a clue. I suppose it could have lost the ability to reflect its user's relationship with the Force overtime, thus casting only light not in the visible spectrum (infrareds or ultraviolets), after being passed on for so many times. Or that, maybe, it's a dead crystal. Kyber crystals are also called "living crystals" after all.
Are there any other interpretations for the Darksaber's color?
Is there canon info clarifying wheter Ahsoka uses the dark side in Rebels?
Are there other theories for lightsaber colors in the canon universe?
Notes:
1. If it is indeed true that red sabers are only revertible to white, then Tera Sinube's extremely white light-blue saber hints that white is also achievable without bleeding the crystal.
2. Anakin's blue saber not having turned red midway through episode III hints that the process depends on meditation with the kyber crystal.
3. Samuel Jackson wanting purple for his saber is not a real explanation. Bad guys vs good guys for red and blue also is not. Tatooine's blue sky for green sabers isn't either.

 

You're reading way too much into the color of a Jedi's lightsaber. Sometimes a green blade is just a green blade.

 

"3. Samuel Jackson wanting purple for his saber is not a real explanation. Bad guys vs good guys for red and blue also is not. Tatooine's blue sky for green sabers isn't either."

those are exactly the reasons.

 

I mean to say that's like answering "god did it" for every minor real question. Not a real explanation.

 

i find the lightsaber colors interesting. this page summarizes them. not sure if that opens to the canon tab, but if not click on the canon tab.

also regarding the light spectrum, i would recommend looking up the electromagnetic spectrum. visual light is part of it. red light has the longest wavelength and the shortest frequency; violet light on the opposite end has the shortest wavelength and the highest frequency.

eta: i like purple being red/blue though because the character of mace is a very aggressive jedi. perhaps purple <= more aggressive warriors, though not on the dark side. somewhat gray-ish.

 

Even if we're talking in-universe, lightsaber colors have no meaning. As seen in TCW, the lightsaber crystals are colorless (not white) until the person connects with it through the Force. When a Jedi makes a connection through the Force with it, it can glow either green or blue. When a Sith enforces a connection through the dark side, it glows red. That's it. There's no color mixing involved. There's no relation to abilities or knowledge.

Windu happened to get purple. Tera Sinube is blue. Ahsoka's sabers are green. The temple guards have yellow.

Anything else is just baseless assumptions and fan fiction.

 

Tera's is vastly paler than "normal blue". It's pretty close to TCW Ahsoka's - which are usually called white.

In the context of the newcanon, it's entirely possible that categories like "Jedi Sentinel" "Jedi Consular" and "Jedi Guardian" will make reappearances. The Holocron (compilation of all EU data) is available to the authors of the newcanon, after all.

 

Hues can vary but the color does not. Sinube's saber is blue. Ahsoka's are green, at least in TCW.

Not as justifications of lightsaber colors though.

 

I don't think you read all the way down. I explained there is no purple in the visible spectrum of light. It can only be made by mixing blue and red light.
You can only dispute that idea if you assume humans in Star Wars have fundamentally different eye biology and neurology than our own.
Now wouldn't that be a baseless assumption?

 

It's just canon and basic science. No other sources there.
I did assume speculative ideas so I could make the theory as deep as it could get, but I did make it explicit that anything speculative was just a possibility in the bigger explanation.
Rejecting the specutalive ideas, therefore, render just alternative versions of the theory and not it's complete refutation.

 

And I've explained that crystals are colorless and that colors are arbirtrary with the exception of red. You don't get a purple crystal by mixing blue and red. You just get purple. And purple does exist in the light spectrum.

No, that's a strawman.

 

I actually checked before I posted this. There is no purple, even though that's a very common mistake people make, to the point of it even being wrongly represented in illustrations.
There is violet, but it is the dark-blue kind of violet.
This video could explain it better, it's from a dedicated channel about basic physics:

And I know crystals are colorless. That's literally in the first sentence into my theory, after I present myself. Again, you're sounding like you didn't read at all.
Lightsaber colors have never been confirmed to be arbitrary, because not yet having an official explanation is not the same thing as being arbitrary; it just makes it seem like so.
I never said you get a purple crystal by mixing blue and red. What I actually said is that you get a purple blade, when the crystal casts red and blue light.You didn't get this the first time because you believe purple actually exists in the visible spectrum, so you didn't stop to think about it. You have misread my post entirely. And that's why you believe my argument is a strawman in the first place.
Plus, not explaining a wrongly appointed fallacy makes a fallacy fallacy.
Sorry for being harsh with language, I just like being serious in discussions.

 

i'm so confused. violet looks like "purple" to me. can we just call it violet instead? or indigo? or whatever?

 

I think Orange is a canon color now because it was in a recent comic.

 

Out-of-universe explanation:

Red, white, and blue were all considered as lightsaber colors in effects tests for SW 1977. At that stage, though, the idea was all lightsabers would be the same color. The 1974 rough draft script describes hero Annikin Starkiller's saber as red. However, after seeing the test footage, Lucas opted to use white "laser swords" while filming. The initial plan was to use glowing electric rods on set to capture the basic lightsaber effect on camera (an idea that wouldn't come to pass until TFA).

It seems it was Ralph McQuarrie who came up with the idea of different saber colors -- in his famous painting where Darth Vader (with a blue lightsaber) battles Deak Starkiller (with a white one).

This idea was implemented in the final film when the first attempt at capturing the saber glow in-camera didn't work, and had to be replaced by rotoscoping. It's possible that Luke's saber inherited from Anakin was meant to be a separate shade of blue from Obi-Wan's blade -- maybe as a nod to the fact that Russians (like filmmaker Sergei Eisenstein) perceive "blue" as two different colors with two entirely different words.

For ROTJ, it was Lawrence Kasdan who first proposed giving Luke a new color of lightsaber, as a way of quickly communiciating to the audience that Luke had built a new saber between films. The ROTJ pre-release trailers show Luke with a blue sword, like the one he used in ESB. However, this didn't show up well against the bright desert sands in the sail barge battle.

Additionally, this early preference for giving Luke another blue sword may be why Lucas and Marquand shot a scene in post-production of Luke assembling the new saber and giving it to Artoo.

PS: besides yellow, orange, and purple sabers, variant shades of standard blade colors also make an appearance in LucasArts' 1997 Jedi Knight game. In that game, the Dark Jedi Maw (who lost his legs in an earlier duel, rather like Darth Maul) has a scarlet lightsaber, distinct from the red color used by other Dark Jedi. The variation was intentional: early JK previews show Maw with a pale green lightsaber instead.

 

the colors change depending on my screen. i'm done. haha.

 

Personally I'd rather Kylo have a traditional lightsaber with a different color then A crossguard with an old color. Oh well.

 

some descriptions have kylo ren's saber as red and yellow or gold (essentially it's like orange).

 

Now you're being pedantic and discussing semantics. Windu's lightsaber is purple/violet. It's been called both.

I did read. The problem is your assumptions. Purple is not red + blue. It's not a light + dark side color. Mace Windu is not a light + dark side user. Crystals are colorless. You get purple the same way you get blue or green. You don't get yellow by mixing green and red. You just get yellow.

If Lucas wanted to provide an explanation, he would have done so in the Younglings episodes. But he didn't. The rules are blue and green for Jedi and red for Sith, due to how each group connects with the crystal through the Force. Hues are irrelevant, those are the colors. And Windu simply happened to get purple when he connected with it (the Jedi way).

That's mixing blue and red, which is what you said. But the point is that you used it as a justification for light + dark side, which is not only unrelated but not how it works either.

 

Oh, yes, I do. I don't see any reason why I shouldn't, unless whatever I'm looking at is explicitly shown as not being the case.

 

Exactly, and I'd happily drop the idea if light hue/frequency was shown to be one of those science twists (even though the difference would actually be in our neurology and not in light physics, called optics, because real color doesn't exist outside qualia). But, for the time being, it still hasn't (and there's no reason to), and that's why I find this theory intriguing.

 

The video? No, I didn't. Nor do I need to.

That the existing colors have no meaning other than blue and green vs red depending on how one connects with the crystal.

Again, Windu's crystal is purple from the get go, no color mixing involved.

What? Evidence is proof. And there's no hint. Mace Windu doesn't use the dark side. His lightsaber color doesn't represent any light and dark side usage/association.

It's a false theory that the movies disprove, if one can call it a theory to begin with.

It's not plausible when the evidence (i.e: the movies) proves otherwise.

Wether I like it or not is irrelevant. I've provided arguments. You provided baseless speculation.

A Jedi having a green lightsaber or a blue one doesn't say anything about his character or MO. To pretend there's a connection is nothing but fan fiction.
