I agree, it would be looking better in green but I think they wanted to give a sort of « blueprint » look to the components!The designer looks amazing but I do feel like the tank component icons shouldn't be blue, as it fits ships but clashes with the usually brown/green color scheme of tanks.
Maybe how it was in older games where you assigned doctrine research to individual theorists?Maybe now we will have different ways of getting new doctrines, a system where you research doctrines with experience so that way we will free more research slots for these new modules would be amazing imho.
