I have green under my 2000 Civic and I have never had any problems, I have even had cops follow me into a parking lot and sit behind me when I got out of the car and they said "Neon Looks Good"...LOL

I live in Atlanta, Ga and have never had any problems, But I have green so thats not a red/blue color issue...LOL. Plus all 4 of my tubes are hidden so they cant be seen anyways.
