To be completly honest, I\'m getting a little tired of hearing people say \"fire should always be painted this certain way\" Fire is definetly not always the same, although there are some principles that are generally true....if you can find a flame color/tempurature chart it may really help.
First off, remember that not all flame is orange/yellow. What color a flame is depends on what it is that is burning.

Secondly, yes, glowing things will often be different than burning things. This is because the hottest part of a glowing thing is usually the center....the part that is the hottest is, in glowing things, the part furthest away from the cold.
I\'ve done a lot of studying flames, as a ceramics major in college (graduated 2 years ago) and it doesn\'t always look the way you would expect it to. Fire is effected by many things, including the amount of oxygen present. A low-oxygen fire looks much different than a high-oxygen fire.
