Look, if you guys could add an item/craftable that allows recoloring of certain parts of the weapon [whether manually or by selecting certain colors for certain shades/parts] that'd be amazing, as modding for a simple weapon recolor is extremely tedious, and for a few weapons, impossible. If this sort of update could make it in Starbound, I believe it'd attract a few people, and for the current players, make them happy. Maybe that's just me, though. Anyways, if you do see my suggestion, hopefully you have the power to add it. Thank you.
there is a mod for this, but it only really works on procgen weapons: https://community.playstarbound.com/resources/weapon-assembly.4277/
