		<description>The color of the flame is dependent upon the energy level of the photons emitted. Lower energy levels produce colors toward the red end of the light spectrum while higher energy levels produce colors toward the blue end of the spectrum. The hottest flames are white in appearance. The color of a fire may also be affected by chemical elements in the flame, such as barium giving a green flame color. The flame color depends also on the unoxidized carbon particles. In some cases there is a partial fuel oxidation due to oxygen lack in the central part of the flame, where combustion reactions take place. In such cases the unoxidized hot carbon particles emit radiation in the light spectrum, resulting in a yellow/red flame, such that of common house fireplace.</description>

		<description>The point of the question is missed? The answer is, &quot;yes&quot;. When a fire burns a similar element that is also present in the &quot;Star&quot;, it will burn at the same temperature therefore emitting the same color if all other relative elements present are equal.</description>

		<description> this is a bunch of bull all fire exibit the same couler pattern just in deferent degrees heat is the magnafacatoin of friction that is why you also see it in the suns heat emission  science 101 abert e</description>
