I'd be rather more worried about people being able to make virtually indestructible ships, or ones that are just better enough, than being able to tweak HUD colours beyond what Frontier currently allow.
i know. we just disagree on who/what to blame. the mere existence of this tool (and several others) paints frontier as the bad guys, and that much was clear just in the op which actually does so explicitly. so you didn't have to look that far, into a tangential side comment about the hud colors.
