You can change the color of the sails whenever you want, as long as you have the gold. The rigging can also be changed. Btw, each rigging upgrade has its own look. If you look closely at the sails, Take Cover has a pattern of dotted lines running down the sails. Full sail has a plaid pattern. Also, each pattern changes the shade of the sail color.
