In general, the hotter a flame, the shorter the wavelengths of light that gets excited, because shorter wavelength photons have higher energy. One can see this most readily from the "black body" spectrum, which bounds the spectrum of a gaseous flame.

Blue flames are hotter than orange, red or yellow flames. In astronomy, the hottest stars are blue and white, while cooler stars are red/yellow. Our sun is in the middle range, with a yellow/orange color. This can also be explained using the energy equation E=hv, where E is energy, h is Planck's constant, and v is the frequency of light. Because blue has a higher frequency than orange or red, it also has a higher energy than orange or red.

As I remember, the hottest part of a flame is yellow, just above the blue part.
