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 ...
The red lithium flame leads to lithium's use in flares and pyrotechnics Copper compounds glow green or blue-green in a flame. Calcium compounds glow orange in a flame.

The colder part of a diffusion (incomplete combustion) flame will be red, transitioning to orange, yellow, and white as the temperature increases as evidenced by changes in the black-body radiation spectrum. For a given flame's region, the closer to white on this scale, the hotter that section of the flame is.
The flame is the visible portion of the fire. Flames consist primarily of carbon dioxide, water vapor, oxygen and nitrogen. If hot enough, the gases may become ionized to produce plasma. [2] Depending on the substances alight, and any impurities outside, the color of the flame and the fire's intensity will be different. [3]
The monster described by Tammas has two heads; [18] the equine head has an enormous gaping mouth that exudes a pungent, toxic vapour, and a single giant eye like a burning red flame. A particularly gruesome detail is that the nuckelavee has no skin; [ 19 ] black blood courses through yellow veins, and the pale sinews and powerful muscles are ...
The flame flared up a pipe, through the Olympic Rings, and on up the side of the tower to ignite the cauldron. The cauldron used in 1984 is the centerpiece of the Los Angeles Memorial Coliseum; it was used in 1932 and will likely also be used in 2028. In Atlanta in 1996, the cauldron was an artistic scroll decorated in red
In Indonesia, Strobilanthes alternata is used to promote urination, check and heal hemorrhages, stop dysentery, and treat venereal diseases. [1]The plant is popular in the United States and rarely the United Kingdom to use in hanging baskets for gardens.The botanical name of Red flame ivy is Hemigraphis colorata Blume.
