Urgh, the aesthetics of mixing /ln with /fo are just plain wrong. I can't bring myself to do it!
I know right!!!!
I've considered just painting a silver stripe on the regular fighters, and then running them as the First Order TIEs if I was so inclined to need them.
Absolutely agree that the /fo paint scheme is just hideous. Heck, it doesn't even make any sense if we assume the TIE panels are solar energy collectors. White would reflect significantly more light, making it terrible for absorption. I mean, there's a reason why solar panels are black (they often appear blue because absorption of light energy drops off in the blue spectrum, so that color gets reflected).
Freaking JJ Abrams just had to put his little stamp on Star Wars instead of just sticking to the formula (like he did with everything else about that movie, lol).
