The color you imagine when you think of that ATLA character :D. (Like I'm thinking of Azula I see blue background for her. Well if you understand what I mean.)
Okay I didn’t even see this one until just now lol. I think it go buried.
Anyhow, I also see her as blue. I think Bryke chose the perfect color for her fire. Blue is calm and calculating. Blue is serenely and beautifly dangerous. Blue is cold anger as opposed to hot and passionate anger. Azula is all of these things to me. Azula is like her fire.
Azula is her fire. Azula’s fire is Azula. The fire was bending Azula this whole time.
