According to 4K77, the engine glow on the X-Wings were red, while the Y-Wings were orange. Some things about Rouge One to me, that was taken from the 2004/2011 “Special Edition / Blu-Ray.”
IDK, those 4K77 engines looked pretty pink (and orangey-red for the Y-Wings).
This may be from the latest D+77, but it’s very much in-line with what the references say about the engines.
