Briefly on the topic of storm trooper camo - it’s entirely unnecessary and counter productive to the narrative and plot devices that the purposefully always white troopers are. Throughout the movies you see their armour take different shapes and forms in different environments that do provide different functionality but they always remain white which points to a higher conscious decision to maintain a stark white armour despite adapting its form & design to the conditions and military engagement.
From a logical viewpoint not taking anything else into account, yes it makes sense from a military perspective to provide forest, desert or urban camo armour as per the environment they are deployed to but this logic has obviously been consciously overriden (as per a GL statement quoted in an earlier post) in favour of the image and message it conveys by all troopers remaining white. It speaks to the might and power of the Empire, a constant and unmissable message conveyed wherever ther are seen, that they need not bother with such tactical matters nor do they ever feel the need even consider such matters as who would raise a hand against the mighty Empire? Until the Rebels off course…
The only military members of the Empire (apart from the Officers) that are not white are the black fighter pilots who primarily will always be on a Star Destroyer or the Death Star or actually inside a Tie fighter and not seen by the general public as well. And then there’s the ceremonial guards in red which again is all about the associated message - it is the colour of blood and is meant to convey fear and awe as it signifies the imminent arrival or presence of the Emperor himself.
It’s all about visual language such as the fact that Vader being all black makes him a fearful figure and really stand out in the Empire against the vast ranks of opposingly stark white storm troopers. Also being the public face of the Empire, troopers being white could be seen as a way to placate and mislead the masses into continual complacent acceptance of their control since white is not generally associated with ‘evil’ but with ‘good’ and so the masses are less likely to care about the Empire’s motives as long as they are generally left alone and will turn a blind eye to events they don’t have first hand knowledge or involvement with.
Ok, maybe that wasn’t so brief LOL…
