Red ink absorbs high energy photons so yeah it tends to get trashed. Mineral reds are good (the red on a red metal barn) and some chemical reds but not others. I remember on Jan 1, 2002 walking around Binghamton where there were many white-grey-and-blue flag lawn signs all over town that had been hurriedly installed the prior September and going in to watch a parade on TV where an announcer said “You know what my favorite bumper sticker is? These colors don’t run”

The flag I got from the US Army in 1993 when my father passed away is still in great shape while many of them don’t look so good.
