Re: They didnt know..? Edit
Before Kurotsuichi and Akatsuchi made their debut, all instances of Iwagakure shinobi were shown with the correct style of flak jacket, but with brown colours. I think the first time we saw them in colour was when Kishimoto showed them in a colour spread. I don't know how often they ask Kishimoto for colour directions. I don't remember if random background Iwa-nin had red jackets as well when those two debuted, but I think that it's likely that if they do, is because production of these episodes was already over before there was the colour spread. I don't know. Maybe in future episodes, they'll be shown with the correct colour. Something similar happened with the Rinnegan. I believe there's an image in that article showing how it was coloured in the anime before it was coloured in the manga. Omnibender - Talk - Contributions 23:17, June 25, 2011 (UTC)
