Not sure if the two are related but I noticed that Sun Warrior Zuko's body paint looks reminiscent of the Painted Lady's body paint. And considering the PL is a Fire Nation spirit...
Idk where I was going with this I just noticed the similarity
It's absolutely intentional! Following the same logic as in Akai Kotou (adding a link for the curious folks out there!), Sun Warrior Zuko chooses his markings to resemble those of the Painted Lady, a retribution/protection spirit of Fire Nation rivers.
This is also my not-so-subtle way of drawing attention to the fact that the Sun Warriors' warpaint and the Painted Lady's patterns actually do resemble each other in canon.
