IMHO, I wouldn't color match inserts, as there are a couple different red inserts, and using red LEDs, you'd lose the difference. I went all warm white in GI and inserts, and had to go for natural white (sunlight) in the backbox because my translight is old and yellowed from the incandescents.
I'm also not a fan of landing planes on my TZ, so I tried to keep the color wash to a minumm.
