So this is my Republic colour scheme. I'm wondering what colour of engine glow I should do. I usually do the classic Star Wars pinky-purple, but I think maybe it should be different on these? I'm thinking a red cockpit canopy, so maybe red? But would both of those be too much red? Any suggestions are welcome.

Old school orange-red might work well, with more orange than red. Or something crazier like a light purple to dark purple.

My advice - choose a colour that you can work easily for this task. For me, there are colours far easier to do engine glows with.

Pinky-purple or orange-red would both look fantastic with that colour of armor

Thanks for th advice guys. I went with yellow in the end, with a darker red cockpit colour.

Just the white to clean up and these are done!
