Here's another take, not straight vanilla.
It's sort of a TOS upgrade, that addresses some issues I have with the three color scheme. Medical (sea green) is split from sciences and security (brown) is split from operations. Picard is wearing the captain's prerogative olive drab. Troi is wearing uniform colors at least, and Wesley is sent back to gray.
Y'know, there comes a point when uniforms stop being, well, uniform
. I'm pretty sure sticking the whole cast in either different colours or different clothes qualifies!
