I once tried to get a Gundam FATE rpg campaign going set in 0080 on a wrecked colony jointly administered by the Feddies and the Republic of Zeon and made it canon that the RoZ military is dominated by "Ralists," basically Zekes who blamed the defeat on the Zabis but otherwise good Contolists.
Zabist bittereinders all went to Axis! Except for the real freaks who ended up in the Delaz Fleet or any other paramilitary org with a marble bust of Gihren ripe for secret kisses
These would be the guys who insist that Operation British wouldn't have wrecked the world if the Tianem Fleet hadn't knocked Iffish off course. They either deny the gassing or play it off as limited strikes against military targets. They haven't figured out how to dismiss Mahalese Zeon like Garahau
RoZ ships are obligated by treaty to have high-albedo color schemes but the treaty didn't make the same provision for suits, & while many still wear factory paint more and more of them are Ral blue & some of them sport officially disapproved House of Ral crests. Crest shows up in RoZ tattoos as well

(I am going off the memories of a manga I stopped reading because the art sucked and also boy oh boy did it sexualize 14-year-old Haman Karn)
