I have come to the conclusion that the preset colours available for our uniforms are insufficient. How did I come to this conclusion? By trying to turn the TNG movie uniform into the correct colour scheme of either First Contact or any episode of DS9 during the Dominion War. The colour of the shoulders on this uniform is a kind of greyish faint lilac. I've looked at pictures of movies and the show ( I have DS9 on my computer so its easy to find a reference point) and simply there is no colour option to match it.
So what do I propose? A colour pallette like the one you get in Photoshop or any real image editor. The ability to select any colour is much preferable to a very limited number of presets. There are 16.7 million colours that my monitor can produce, but STO apparently only offers a few dozen. Granted this is a decent spread, but it doesn't hit the mark between too purple or too grey or too blue that you need to get the effect of a real DS9/First Contact uniform.
Why does it matter that I can't get my DS9 uni correct? Because they gave us that uniform but we can't get it to look right. Ive settled for now for some purplish colour thats not bad in dungeon lighting but its still obviously wrong.
Its not much to ask and we already know the game is capable of this much colour variance because of the lovely phaser colour mod bug. I think this is an appropriate improvement to the idea of huge character customization.
