At 1500 C, iron glows “[dazzling white](https://en.wikipedia.org/wiki/Red_heat)”.
At roughly 2000 C, [propane](https://en.wikipedia.org/wiki/Gas_burner) burns [blue](https://en.wikipedia.org/wiki/Gas_burner#/media/File:Propane-burner.jpg).
At 3551 C, [Mu Cephei](https://en.wikipedia.org/wiki/Mu_Cephei) earned the name “Herschel’s Garnet Star”, and this is not a reference to uvarovite.

Flames glow depending on the elements being burned. Copper for example makes a green flame, sodium a blue one. There are thousands of chemicals you can burn to make colors. Thats how we color fireworks.
Stars glow according to black body radiation, which will dictate the color anything will glow at a given temperature.
[Here are some graphs to help explain](http://hyperphysics.phy-astr.gsu.edu/hbase/wien.html) basically the hot stars let off all sorts of wavelengths, but the combinations of these wavelengths add together to.make a certain color in our eye. The sun, a yellow star, actually emits a peak wavelength that is green, but since it’s still emitting a ton of red wavelengths, it averages out to a yellow color
