I been trying to recolour the purple part of my ship for a while and I can’t find a spot that lets me do it. I redocked my ship and this part seemingly isn’t controlled by your clan’s colours (my clan has red/grey for its colours, so purple shouldn’t be here if that’s true). Genuinely out of ideas on what to do with this lol
Pretty sure you can’t
The updated brig models carried over the colors from before full release but they neglected to add a way to recolor that part
So stupid if you ask me
I know how to color it…
BUT I WONT TELL YOU 
Stand up in the crow’s nest and look down, is what I’ve heard for that. Never tested it though
Bugged iirc
