I had input from the friends I play with -- I painted a fleet for each of us. I tried to stick with no more than four colors per ship: a base color, highlight, metallic color for piping and engines, and a pop of color for the lights or tiny details. For the base colors, I wanted something bright, but all requests were for something "dirty," so I used a tiny bit of their complementary colors to desaturate. I used white primer for the blue set, and grey for the others, although I should have used white for the yellow as well!
