It’s all relative
I don’t know about blue but here is all the math to turn a red light green… Don’t think of doing it though while you could probably get out of a ticket for running a red light I don’t even know what the fine is for driving many thousand times the speed limit is.
Edit: just realized I forgot to post the actual link… https://sciencenotes.org/fast-go-make-red-light-look-green-relativistic-doppler-effect/#:~:text=If we take the speed of light to,to convert to km%2Fhr%2C you get 197%2C640%2C000 km%2Fhr.
To bad the traffic light is in the speed radar’s reference frame, when your licence plate is on the photo I doubt the judge will care that your yellow car is clearly blue in the photo
