I've been playing X-Wing vs Tie Fighter lately, and I love the different squadron markings on the various fighters. I've begun painting marking stripes onto my TIE Fighters to see how they look -- if it doesn't work out, it's easy to fix. I've chosen two thin orange stripes, horizontal, near the top and bottom of each solar array. I may do the same to my Interceptors when I get some.
I'm planning to do my rebels in green.
Anyone else go with a different colour scheme? I'd stick with black TIEs and red X-Wings, but I'm something of a hipster -- I've got to be different.
When I get the stripes done I'll upload pictures.
