Yellow-Green
Lead compounds tend to be blue in flame tests
Cupric nitrate typically produces a blue-green flame when burned.
Selenium nitrate typically gives a pink or reddish flame color when subjected to a flame test.
Aluminum nitrate does not produce a specific flame color when burned. The flame color produced by a compound is typically due to the metal ion present, rather than the nitrate anion. Aluminum itself does not produce a significant color in flames.
I presume you mean silver nitrate. A flame test detects only the metal ion in a compound. There isn't one for silver.
Aqueous barium nitrate is colorless.
Barium salts, such as barium chloride or barium nitrate, are commonly used to produce a green flame when burned. The green color is a result of the specific wavelength of light emitted by the barium ions during the combustion process.
The flame of strontium nitrate is red. It produces a bright red color when ignited.
The flame color of barium burning in oxygen is green.
Lead compounds tend to be blue in flame tests
Cupric nitrate typically produces a blue-green flame when burned.
Selenium nitrate typically gives a pink or reddish flame color when subjected to a flame test.
The color of barium in flame is pale green.
Iron nitrate typically produces a yellow-orange flame color when it is heated. This color is due to the presence of iron ions in the compound.
Barium nitrate is used in fireworks as a green colorant for the flames. When burned, it produces a bright green light due to the barium ions emitting specific wavelengths of light. This gives fireworks their characteristic green hue.
Aluminum nitrate does not produce a specific flame color when burned. The flame color produced by a compound is typically due to the metal ion present, rather than the nitrate anion. Aluminum itself does not produce a significant color in flames.
Barium produces a light or apple green flame when held in a hot clean burning gas flame. it could be confused with the different green flames produced by copper, boron, molybdenum, antimony, tellurium, thallium, phosphorus and others.
