That's because Airways paid for the paint jobs and JO doesn't want to have to pay to upgrade the interiors. A paint job is easy to pay for; the interior mod isn't. You have to go to the seat vendors to manufacture a new color code. Then you have to go to C&D Zodiac to get new interior panels and lav doors made with the new color code. New carpet is a must as well a floor mats for the lavs and galley. I know United was on JO's butt about cabin cleanliness and mx upkeep, but I think they gave up after a while.
