Barium Chloride becomes a yellow/green when heated
Barium chloride typically appears as a white crystalline solid.
Barium compounds, such as barium chloride, are often used in fireworks to produce a green color when burned. When barium salts are heated, they emit green light due to the energy absorbed and then released by barium ions.
The color of barium in flame is pale green.
When heated gently, the red burgundy CoCl2.6H2O will decomposes into the violet CoCl2.2H2O then to the blue anhydrous CoCl2. Note: When this anhydrous compound is dissolved in water it will go back to the original red burgundy color.

The final solution color will depend on the concentration of barium chloride and potassium chloride. However, in general, barium chloride is white and potassium chloride is colorless, so the final solution will likely appear white or colorless.
The precipitate formed from the reaction between barium chloride and potassium chromate is a yellow solid known as barium chromate.
White.

Barium chloride (BaCl2) is a white, colorless solid in its pure form.
Barium chloride can be identified by performing a flame test where it will produce a yellow-green flame color. Alternatively, it can form a white precipitate when mixed with a sulfate compound, such as sodium sulfate, due to the formation of insoluble barium sulfate. Additionally, using analytical techniques such as spectroscopy or chromatography can confirm the presence of barium chloride in a sample.
The flame color of calcium chloride is typically a deep orange-red color. This color is due to the presence of calcium ions in the compound, which emit this characteristic color when heated.
