The color is due to the radiation emitted by copper.
It needs to be open to create the hot, blue flame that roars. If the air hole is shut, the flame will burn yellow, similar to a candle.

The four MAIN IONS in seawater in descending order of abundance are: CI: Chloride Na: Sodium SO4: Sulfate Mg: magnesium Found in Leckie-Yuretich: Investigating the Ocean, Page 114, Seawater Salinity: The salt of the Ocean
Under IUPAC naming conventions, AlCl3 is called aluminum chloride. It is also commonly called aluminum trichloride and aluminum (III) chloride.
Mercury(II) Chloride
Cupric sulfate and chloride are blue; also cupric carbonate is blue but not soluble in water.
Pyrotechnics, it burns blue-green
CuCl2 if it is Cupric Chloride Anhydrous CuCl2.2H2O if it is Cupric Chloride Dihydrate/Dehydrate.
Cupric chloride can be made by reacting copper metal with hydrochloric acid. The reaction produces cupric chloride and hydrogen gas. The cupric chloride can be isolated by evaporating the resulting solution.
CuSO4 + H20
The formula for cupric chloride is CuCl2, where Cu represents copper and Cl represents chlorine.
If you add Copper in Cupric Chloride at the time of reaction, it will turn into Cuprous Chloride. But it will again turn into Cupric Chloride if you continue the reaction. This is actually a Exo-Thermic reaction.
The solution color of cupric oxide is blue to green.
Cupric chloride refers to the compound CuCl2, where copper has a +2 oxidation state. Cuprous chloride refers to the compound CuCl, where copper has a +1 oxidation state. This difference in oxidation state affects the chemical and physical properties of these compounds.
Formula: CuCl2
Mix with water and filter, Cupric oxide will be filtered away while sodium chloride remains in the solution
Ferric chloride burns with a blue/green flame.
