In fact, I think Uhura and Nurse Chapel might have been the only prominent female officers to not wear red, and Uhura quickly switched to wearing red.
Quite a few guest star crew women wore blue. Some of their characters: Helen Noel, Marlena Moreau, Carolyn Palamas, Mira Romaine.
But there were more who wore red than blue or gold. Also, I wouldn't count Marlena Moreau since she only wore the mini skirt uniform in one scene.
There being more reds than blues or golds is not what you said in the first place.
I think we can count Marlena Moreau as a blue, unless you're going to claim that Uhura didn't wear red for the majority of "Mirror, Mirror"?
