[REQUEST/HELP] Engine component colouring

[Axeface]

Ide like to make a request. The Pink/Green/Blue of the different engine options in the game dont go with any of the paintjobs, or even the 4 default paint schemes that you can select on the empire screen (and even that wouldnt help because that is an empire wide option and they arnt available as paintmods!!). It makes every ship look incomplete, and the colours chosen for them are really not nice to look at imho.

Is it possible to change this? For me the best way would be to make the engine components fit each paint mod specifically. Or how about making all the engine options a colour that will fit with everything, such as a dark grey/black?
Another option would be to make the engine colour fit with the 4 default empire paint schemes? And it would be great if those schemes were actually turned into infinite-use common quality paintmods instead.

Ide also like to ask how all this is actually handled by the game. As far as I know these colours arnt a simple texture? Is it possible to change their colour for each paintmod?

Edit: I've been looking into this - checked the xmls and the textures but coudnt find anything that seemed to control colour there. The engines actual models have some vertex paint that might be how its handled? Not sure if the import method is working properly for this as it doesnt look right.

EDIT2: This has me stumped. The textures "assets\textures\paranid\par_engine_trim_glow" have colour, but changing this texture is doing nothing in game. The material_library.xml doesnt have any colour settings for par_engine_trim either. Can anyone assist?
