I've only seen one other person have this issue, & it was fixed by leaving the drydock to do a railjack mission & coming back. I've tried that multiple times multiple ways, with & without other people, & make sure it's all on MY ship as that's what they said worked
I've tried fiddling with all the colors, resetting all the colors,make sure to hit accept every time. I don't have the option to remove this polychrome or fund construction.
