Alice was completely unaware that there was anything special about the flame she had summoned.
In William's alchemy book, everything was explained very clearly, except for the significance of different flame colors.
From a scientific perspective, a flame occurs because the atoms of a substance gain energy at high temperatures and release this energy during electron transitions.
This energy is emitted in the form of light.
Since different atoms or the same atoms in different excited states release different amounts of energy, the color of light emitted by burning different substances, or the same substance under different conditions, varies.
Hence, the same substance can produce flames of different colors at different temperatures.
Red and orange flames are typically around 3000 degrees Celsius, yellow and white flames are around 4000 degrees, while cyan and blue flames reach temperatures of 5000 to 6000 degrees.
