Gun mark colours

[Crazybunny28]

Hi there, just wondering, I've been scrolling through the Modpack and I've noticed that some other people who use aslains are able to change the colours of their gun marks, it's probably flying over my head but I can't find the add on to do it, any help would be appreciated.
