It might be simpler for HTC to make the colors match the color of the lines you pull for your covergence in the hanger.
Thing is though, those do not even match.
Take a look at the Mossi Fb Mk VI's .30 cals, then look at the Spit 9's, then the P40C, then the C202, etc. I inquired about this once upon a time I do not remember what became of it. Do a search and see what you come up with.

There are up to 4 different convergence lines, iirc. At one time I thought the colored lines meant primary, secondary, and then tertiary, etc. However, we only have primary and secondary triggers.
