Azula was the only known character able to create blue fire, but could/should other characters have this and/or a different color in the future of Avatar?

The episode The Firebending Masters showed that fire comes in many different colors. And so, would this be something fans would like to see more of in the series?

I think in the future it can be introduced, but it shouldnt have been in atla. Takes away from it being special.

There may be some individual people from the past (before ATLA) and the future (after ATLA).

I'm mad we didn't see blue fire in tlok with the better animation but I can let it go.

However I think azulon if anyone should have had it. she was named after him and he was a prodigy just like him.

If they do another project (hoping they dont) it should be about the first who used blue fire

No. It’s a unique personal trait to stimulate Azula’s character.

It is mainly an audience thing. A lot of people say that she technically isn’t blue firebwnding but it’s more of a visual effect to show character, but also she is very skilled that it could be true that she has very hot (blue) fire.

Honestly, I think it'd be interesting to see a perfectionist Avatar who has blue or even violet fire because of that.

Other characters could bend blue or other color flames

More blue fire benders but also white, violet and even ultra violet for sneak attacks (mabye Azula could do the snak attack as she gets more unstable)
