For my playthrough, I wanted to do the following for preferred aesthetics:

1) Changed Corsec to Mandolorian ship models.
(done - graphical_culture="mando_01" in 00_top_countries).

2) Make sure Corsec has access to Mass Drivers tech.
(done - add CorSec's empire class to if/then statement under Mass Driver Tech level 1 in swp_all_techs)

3) I want to change the empire laser/turbolaser color from red to blue.
Having problems figuring out this last one. 00_top_countries has a commented out line noting the assigned weapon color for a given empire, but there is no indication as to where or how that color is being assigned. I went digging around in the common folder's data files and could not find anything obviously linked to controlling the weapon color. Has anyone figured that out, or would a dev that knows be so kind as to tell me where I should go? Thanks for any assistance.
