@girr(View Post) A gas flame is like a normal flame in real-life. Note that normal fire can turn blue if it is hot enough. Also blue-hot fire is not shorter.
If we would go into details in TPT, then we would have flames such as green and purple flames (from lighting salts on fire using flammable substances) I think it's nice how it is... but not all gasses are the same...we already have oxygen which has a yellow flame. And im sure that it is no specific gas. If it were then it would say.
