This is randomania. Lucas assigns colors and you assume they're chosen at random.That's not symbolism. It is just a way to help the audience quickly identify the two different sides. The actual color that each side was assigned is irrelevant. If you reversed the light saber colors, you'd have the exact same movie.
When Lucas says "that's just the way it works." He is referring to each side being assigned a team color, not that the colors themselves have any significance. You are reading stuff into that isn't there. But then again, you are a chronic sufferer of apophenia, so it is to be expected.
In case you have never noticed it before, whenever two sports teams battle it out on the playing field they each have different colored uniforms. Even in war, each side typically has a different colored uniform. It really helps everyone involved tell one side from the other, but the colors themselves are irrelevant.
BTW, white is usually associated with purity, perfection, honesty, and cleanliness. "White is clean, simple, and pure. It stands in stark opposition to black, and its meanings are unequivocal. As white light contains all the colors of the spectrum, it’s an inclusive, impartial color, favoring no single hue and refusing to take sides." https://www.sensationalcolor.com/meaning-of-white/
The Storm Troopers are dressed in white. If Lucas was concerned with symbolism they would have been in some other color.
Your theory about colors is bunk.
Top Google hits for what each color symbolizes:
Green as a Symbol
Since most plants are green, the color often represents nature or the environment. Green can also symbolize good health and vitality. This color may also be used to signify balance, fertility, and renewal...
The color blue represents both the sky and the sea and is associated with open spaces, freedom, intuition, imagination, inspiration, and sensitivity. Blue also represents meanings of depth, trust, loyalty, sincerity, wisdom, confidence, stability, faith, and intelligence.
The color red can symbolize many things, including:
Danger and sacrifice
Because red is the color of blood, it has historically been associated with these concepts.
When Lucas says "that's just the way it works," he's telling Jackson that those are his only options.
Nobody needs help telling who is on which team in a one-on-one duel where one guy is wearing full-body black armor. The significance is the subliminal associations.
And you're putting words in my mouth. I never said that every color in the movie was symbolic. My guess about stormtrooper armor is that Vader was going to be black for symbolic/intimidating reasons and they didn't want the stormtroopers to be black as well. Plus, the empire has a neurotic ideology of racial purity.
But I never said that every color choice in every movie had a symbolic meaning. Why is the millennium Falcon the color that it is? Why is Chewbacca's fur the color that it is? For no significant reason I can detect.
But when you see a significant choice made in a verifiable pattern, there's more being said than meets the eye. That's what you're missing.
