Color temperature in flame effects comes from the flame’s temperature and the light emitted by the burning chemistry, which is set by three interacting factors. The type of fuel establishes the baseline chemistry and how hot the flame can get, as well as whether it tends toward clean burning or soot formation. The air-to-fuel ratio controls how completely the fuel burns, which directly influences flame temperature and the amount of incandescent soot that glows, altering the perceived color. The combustion conditions during operation—how well the fuel and air mix, turbulence, confinement, pressure, and other operating factors—shape the flame structure and local temperatures, further changing the color output. Because all three aspects interact to determine the observed color, you need to consider fuel type, mixture, and operating conditions together. Focusing on only one factor can lead to mismatches between expected and actual flame color, since soot and temperature effects can override even a seemingly favorable fuel or ratio.
