Tornado GR4 - Panel Indicator Colour
 

I’ve noticed that some instrument panels on Panavia Tornado have different colour lamps/indicators. I presume it’s because some are NVG compatible but can anyone tell me why some appear green and others appear pink. I have an Environmental panel which includes the non NVG orange colour (used on GR1) and also two panels from a GR4 which are NVG compatible but appear either green or pink (when unlit). Was there a reason they went from green to pink or vice versa?
TIA
