Colored fire is a common pyrotechnic effect used in stage productions, fireworks and by fire performers the world over. Generally, the color of a flame may be red, orange, blue, yellow, or white, and is dominated by blackbody radiation from soot and steam. When additional chemicals are added to the fuel burning, their atomic emission spectra can affect the frequencies of visible light radiation emitted - in other words, the flame appears in a different color dependent upon th… WebThe GHS system, part of OSHA's Hazard Communication Standard (HCS), consists of nine symbols, or pictograms, providing recognition of the hazards associated with certain substances.

For most flames, the color is simply a measure of the temperature of the glowing gas. The spectrum of the flame is fairly close to a black body, with a bluer peak in the spectrum indicating a higher temperature. So what you are seeing is that the flame is hotter lower down. This can be seen in gas jet flames or in match flames. highfield bot
