The colour of a star is determined by its temperature, the hottest stars are blue and the coolest stars are red. The Sun has a surface temperature of 5,500 degrees Celcius, its colour appears yellow. The energy produced by the star is by nuclear fusion in the stars core.
Why blue star is the hottest?
The color of a star is linked to its surface temperature. The hotter the star, the shorter the wavelength of light it will emit. The hottest ones are blue or blue-white, which are shorter wavelengths of light. Cooler ones are red or red-brown, which are longer wavelengths.
Does pink fire exist?
As copper heats up, it absorbs energy that's manifested in the form of a green flame. A pink flame, on the other hand, indicates the presence of lithium chloride. And burning strontium chloride will create a red flame. Of course, you should avoid burning chemicals due to the potential health hazards it poses.

Is there black fire?
This is black fire. When you mix a sodium street light or low-pressure sodium lamp with a flame, you'll see a dark flame thanks to the sodium and some excited electrons. “It's strange to think of a flame as dark because as we know flames give out light, but the sodium is absorbing the light from the lamp.
How hot is purple fire?
The color of the flames is apart of temperature affected also by the type of fuel used (i.e. the material being burned) as some chemicals present in the material can taint flames by various colors.
