I really liked what difference the change of the color of the markings on the Nebulon-B Frigate did and decided to do the same thing to one of my Corellian Corvettes. Very simple paintjob, changing the red markings to green.
Originally I had no plans to do any changes to my second corvette. This changed after I saw the season 1 finale of Star Wars Rebels shortly thereafter. I really liked the paintjobs of the three corvettes shown in this episode. Two of the ships sported the markings from the original trilogy in blue, but one had different markings, which set it apart. I decided to apply this markings to my second corvette.
Removed all existing markings by painting over them with the base color of the model and then applied the new blue markings. Really like the result.
