Heres a couple more suggestions to mull over.
How about a half and half paint scheme, port side colourful as required for 'showing off' and photo ops, then you ensure you always park with that side towards the cameras. Then the starboard side in camouflage. Then in a hostile environment you always keep the starboard side to the enemy.....
or
there are now plenty of flexible plastic displays being developed. You could coat the entire aircraft in these and change the paint scheme at the click of a mouse. Then it could be rented out or you could sell advertising space on it. You could even have adaptive camouflage for example displaying the ground below on the upper wings and the plane would practically vanish..
