Another quirk involving the original series’ tunics were the colors - in particular, “command.” Trekkies everywhere will swear Spock wore blue, Scotty wore red and Kirk wore gold. Wrong. The three Starfleet colors were blue, red and green. Lime green, to be exact. “It was one of those film stock things;” Theiss states, “it photographed one way - burnt orange or a gold. But in reality was another; the command shirts were definitely green.” As further proof, look at the wrap-around tunics as well as the dress uniform tunics of Kirk’s – all green. They came off as their true colors because they were constructed of different materials than the standard duty command shirts.


For me, the deciding point comes from what color they made the merchandise. You’ll find a rare item in green, but 90% of the items out there are in yellow.
To me, that’s a decision to make yellow canon.
IMO, the yellow uniforms also look better than Kirk’s tunic green, so it ended up being an accidental improvement.
The colours and cuts laid out in Franz Joseph’s Technical Manual are authoritative. They’ve got authentication stardates and everything.
I mean that document lists “tenne” as the color, which doesn’t seem right to me at all.
I thought it was “taupe” for some reason but I can’t find where that would be suggested.
Closest I could find, from Wikipedia:

I agree I wouldn’t use that word to describe the colour, but it looks just about right the way they print it on the “Uniform Color Code” uniform colour code page, so that’s just a question of what you want to call it.
