I'll try to touch on points in order as best I can...
E1-3 who's gets darker then ultimately black? vader(annakin) as sith
Anakin in the prequals doesn't really have much "darker" stages as far as his costume design goes... The child version of him sports a Padawan's outfit... But come AOTC we jump right into the robes we see him in even as a Sith... So there's a hole in your theory as far as Anakin's "change". The Vader suit as an end result doesn't change that he was Sith before that, and wearing his Jedi Robes he wore for most of one film and most of the previous one... Not much real change there then with Anakin actually... At least nothing that correlates with his ACTUAL physical transformation over time that we can witness.
E-4-6 who does it here?, duh luke. ( and please don't over ANALyze and tell me
what's a standard uniform ect.. . . just look at the colors simply
As far as Luke, I don't think anyone's overanalyzing you Slothus, and nobody's being "Anal" as you so eloquently put it... It's a simple fact that Luke's outfits in ESB were uniforms, not really mental choice on his part, which is an important aspect to consider I think. I'd think over-analyzing it would be implying the colors mean something actually, whereas the simple answer is that Luke's outfit in ESB (well, most of ESB) is just a Pilot uniform... It's not even terribly darker than his Tatooine clothes, and if you compare it to his pants it's not really a change in color at all hardly.
The more important outfit is his black one from ROTJ though of course, and while it is obviously a dark outfit, no denying that, The character's level of "darkness" or evil/bad is highly suspect... Luke's changed but I've never seen him as anything but grown for the better rather than the worse.
His arrogance and overconfidence are more sithlike- He knows he's a badass now and shows it in his calmer(no more giddiness) speach with his friends, sister
and above all he freakin' confidently threatens jabba on the skiff!
Is it really "over"confidence? If it was, he'd have been beaten I think... Palpatine referenced over-confidence being a weakness, but that was based on Palpatine's thought that the Alliance would succumb to his trap. They didn't, and without Luke's help, so he wasn't even over-confident then either.
Luke went into the Jabba situation, and handled himself perfectly fine... He freed his friend(s), he gave his enemy ample opportunity to walk away from the situation... He saved the day.
He didn't even threaten Jabba, Jabba threatened him... Luke gave Jabba multiple opportunities to end this peacefully, and even with compensation, and Jabba refused... Was that arrogant to "whip some ass" then? Hmmm, that doesn't seem right to me.
Luke was confident... Not overly confident, and he was downright afraid of his situation with Palpatine/Vader. As a matter of fact, Luke explicitly makes it clear that he made that last effort to turn Vader to the light side, but he knew it was likely a futile attempt so he was willing to sacrifice himself on the Death Star, so long as he, his father, and Palpatine were destroyed together.
Self-sacrifice for the greater-good is hardly an immature concept, or something a person with "bad" intents is going to consider.
But let's look at something else too... You noted his "arrogance and over-confidence" as being "sith-like".
But what about these situations:
-Was Mace Windu "sith-like" confronting Dooku?
-Was Mace WIndu "sith-like" refusing Dooku's offer of mercy?
-Was Yoda "sith-like" when he marched into Palpatine's office, and exchanged what I hardly consider a humble back-and-forth with Palpatine?
-Was Mace Windu (& Company) "sith-like" when they went to detain a suspected Sith-Lord?
-Was Kenobi "sith-like" when he confronted Grievous twice?
-Was Qui-Gon "sith-like" when he told the Naboo to leave and let he and Obi-Wan handle Maul?
The point with all those instances is that each of them showed EXTREME confidence. Some to the point of legitimate "over-confidence". I would hardly label Yoda, or Mace as ever being "sith-like" though. There's a fine line between confidence and arrogance...
Anakin gets the "arrogant" label because he's a brat most of the time... He openly talks of his superiority to Obi-Wan, his mentor and master... Someone he even refers to as a father-figure of sorts. Anakin EARNS that label pretty clearly.
So, is Luke really "arrogant" or confident? I think he's just confident when appropriate... He's unsure of himself facing Vader and Palpatine, his ultimate test as a Jedi. That is maturity as a Jedi from where I stand. And ultimately he's never over-confident in Jedi... His plans pan out better than he even imagined at the end when he expected his own death (and hoped for the death of Vader/Palpy).
And there's a number of moments where Luke showed a lot of growth and maturity into a great Jedi during ROTJ besides what's discussed. It's throughout the film really.
In Empire though, Luke's over-confident going into the tree on Dagobah and is floored by the scenario... Later, his "attachment" sways his judgment and he flocks to Cloud City to save his friends and confront Vader too early, defying both his mentors who tried to stop him. He paid for it dearly too, and was lucky to survive the encounter.
If anything... Luke's character is immature, and flirted with the darkside more consistantly in ESB than ROTJ where he only succumb to the darkside (once again via "attachment") upon Vader's taunt... He actually bounces BACK from that dangerous edge he walked though. That's maturity defined I think, in Star Wars terms. [/end nerdy comment] hehe
So these thoughts make me think even less of the notion that Luke's outfits by the films are a visual metaphorical progression of Luke "getting badder".
But, a key to think of is "bad" and "badass" aren't the same thing... Being "sith-like" is bad... Being a badass though, just implies you can handle your business and you know it. What the lines are that divide the two are what's blurred.
The conversation certainly grew and spiraled some, but it's important to understand Luke's state-of-mind in the films to judge how the color of his costume may be some metatphore though, so it's all distinctly related material that's for sure. Just a very in-depth topic.
Was lucas trying to show how luke was a lot like his father before him-but then ultimately luke made the better choice?
On this point, Lucas WAS showing some relationship between the black of Vader's costume and Luke's. I've seen Lucas note this in documentaries involving ROTJ. But does that mean Luke's outfit can be paralleled to Luke being "bad"? There-in lies the question, and simplying tying the two characters together doesn't mean one's black outift necessarilly meant he had a "bad" side to him either.
Of course, Luke does have some bad side to him though... He's human, he has to, but the question is can he control it? In ESB he couldn't, in ROTJ he could, so this doesn't hold well to Luke's costume colors being too representative of his character really.
I don't see how getting darker as you get older is a sign of maturity
LOL- what are you saying? That if I wore alotta black in high school(see death punkers,goth) then I'm mature then? but now that I'm elder I wear lighter clothing I'm immature? That I should go with the goth thing now as an old man to look "mature" lol...hillarious .
I think that looking at the colors as a sign of maturity can be taken several ways... it can be looked at as not applicable at all for sure, but Luke's black outfit is plain, it's simple... It's setting Luke apart from the organization (Alliance) while not being bright, vibrant, or "loud"... So it's setting Luke apart but not "seeking attention".
As I've said, after reviewing things in-depth I'm really of the opinion that Luke's outfit is more a tie to Vader, but not a represenatation of the character being "bad". The character of Luke in ROTJ is a much more mature character to me, irregardless of the costume he is wearing, while his lighter costumes in ESB are equally unimportant as to the representation of the character's personality at the time since he is much more immature at that time.
I think the black always represented a badass mentallity/portrayal- challenge me on it....look at all the modern movies- who's the bad guys? or the "badass" good guys? I>E> blade, batman,van helsing,darkman. Bad dudes that ride the edge of totally bad- A sign of maturity?...hmmm,really?
Once again though, "bad", and "badass" aren't the same thing by a longshot. "badass" can be a completely good or bad person... That's intent behind the actions.
"Bad" is just simply someone whose actions are motivated by bad intents. Palpatine is bad in ROTJ, Vader is a torn character as we find out, and Luke is good (a strong, mature Jedi Knight) in ROTJ by my calculations... Luke is a "badass" though too, obviously. He can handle his business in almost any situation and he's confident in himself, even at the very end when he turns the darkside temptation away.
My conclusions on the subject are then that Luke's costume doesn't correlate with his personality if we're discussing Luke being "bad" or "sithlike". There's nothing substantial there to back that in my point of view...
Is Luke "badass" though? He's confident and sure of himself in every situation except his final trial against Palpatine and Vader. To me that makes him a badass for sure!
But not a "sithlike" character or "bad", etc.
