Star Trek and uniforms has always been a bit of a mixed bag for me, but then again, I'm me - but I'll try to adumbrate:
The "monster maroons" looks great... on the big screen. Especially after the "Studio 54 tight pajama party" outfits that 1979's "The Motion Picture" put out, which also happened to be and by far the most revealing of any Trek uniform design. Not that there's anything wrong with that, but TWOK does restore a certain look that means "we mean business, even if we need several retakes because we've sweat so much into them that everyone else trying to breathe is gagging from the stench."
And yet, I could have opened this novella with "Considering how TOS didn't always obey (but more often did) its own colors on occasion as means of department or division, was made when color TV was new, and if you're a Security guard then you don't want to look like an easily visible target. Bright bold red would be the dumbest color for humans to use, since most species on Earth that aren't colorblind will recognize red in one of two significant ways (that of "must be dangerous", or that of "readily visible, easy pickin's target practice"). Since the galaxy was full of unknowns, it actually makes more sense to dress 'em all in red because they're dangerous. Sadly, in TOS, used to show how big and bad the baddie is, red ends up more for the easy pickin's target practice instead, hence all the dumb
red shirts jokes.
By 1987 and we're all used to the big expansive uniform style, now we see TNG in 80s angles versions of the 1960s originals, but as tight as the 1979 spandex jammies were. And yet, color TV was no longer new by any measure and the use of these hues seemed corny at the time, as well as a step back from the imposing fare that the movies brought out. No worries, TNG's color designations grew on some of us detractors and some of us have come to accept that the red/blue/yellow style is simply iconic to Star Trek. Case in point is when Scotty appears in "Relics", juxtaposing movie style uniform (with TOS transporter noise?) opposite the TNG crews' pajamas.
Then came 1996...
...all black with gray quilted tops and a collar indicating division. It seemed unimpressive at the time, but in some ways is actually very practical. Maybe the most practical, but they still looked silly in a way. Silly, if not too generic. Possibly because the producers knew that the TV shows would have the same style creeping into their shows.
Where am I going with all this I no longer remember, except that I really liked TWOK's outfits at the time, even if they weren't always practical. After all, the security folk and some engineering folk had tidied-up TMP uniforms and were clearly a lot more usable for what they had to do.
Oh, the colorized tunics of the STIV cast photo don't do much for me either, apart from reminding how the red/green/blue thing was a relic of 1960s "shiny new color".
This is what I had in mind: Star Trek The Motion Picture:

Actually, the recolored TMP one looks surprisingly good overall. Except Kirk's head is floating due to the slightly mismatched hues combined as a pasted layer on top of the blue coloring for McCoy/Chapel/Spock... crap, now I wish TMP was filmed like that because the color scheme truly is iconic and thus proving your point 100%, and even was when the show was just doing it as a gimmick to sell color TVs. So why can't that TMP colorized photo there be backlit in 8 zillion colors like the lovely cast photo from season 2 TOS (at the end of "I, Mudd") because TOS's use of color may have been 60s, but it still looks sumptuous to this day?
A takeover leads Kirk to his old nemesis, Harry Mudd. Spock and Dr. McCoy are walking through the corridors of the USS Enterprise, where they encounter Crewman Norman, who joined the Enterprise crew only 72 hours before. McCoy mentions that Norman is odd and unemotional; for some reason, Spock...
