Quoted from PanzerFreak:
All depends on how the LE artwork looks. I'm thinking green may be the way to go through considering that that green is used in the Alien logo, there's green rubbers in the game, the aliens acid is green and hell a lot of people think aliens are green, lol.
The second film, Aliens, has more blue tones on its official poster and at times there is a blue cool tone to some scenes in the film. I think that is why Heighway offered blue as another trim option. If the LE artwork has a blue Aliens vibe to it then blue may be the way to go.
Shiny / Jet black would be my choice.
There is enough going on with the art package in this game and lighting it doesn't need eye popping rails, etc. Plus black would "hide" the otherwise more noticeable bezel around the top of the glass a little better, look classy, and would work for any future Heighway game kit that you might drop in.
