I’ll make this short and simple, this was likely already suggested too, but anyways.
Painting UI is placed in the boat menu.
Yknow, with everything else.
And each group of the boat is just an easy to use “Click this, then click the color you want to set it to”.
No, this won’t give you a free boat colors gamepass. (Though.. why is this even a paid thing to begin with?? I can atleast understand animations and magic circles, but why boat colors??)
