I can't fine any good color patterns for the Aventine. On my previous ships I would use Corvus (or Corvous, I forget) pattern with the darkest black color with the Aegis set. But Corvus doesn't work with the Vesta and the Aegis visuals look like crap (The warp trails only go out of TWO of the six impulse engines ). So I have been using the Vesta skin with the colors on darkest black, with makes the light blue turn navy. But that is the best I can get and it still doesn't look good.
